Which Fuel Releases the Most Energy Per Mole Measure by Heating Water :: Papers

Which Fuel Releases the Most Energy Per Mole Measure by Heating Water Hypothesis In this investigation I will burn alcohols to heat up a beaker of water. I will be burning five fuels which are called Methanol, Ethanol, Propanol, Butanol and Pentanol. In my investigation I predict that the alcohol Pentanol would release more energy than the other alcohols because as the chain length of the alkanes get longer, the more energy is released. Apparatus  · Retort stand  · Clamp  · Measuring cylinder  · Thermometer  · Heatproof mats  · Copper can  · Splint  · Chemicals(Methanol, Ethanol, Propanol, Butanol and Pentanol) Independent variables  · Using the same scales  · Same amount of water in copper beaker  · Same height of thermometer from water  · Temperature of water before experiment  · Weight of alcohol before experiment Fair Test To make it a fair test:  · I made sure I put the same amount of water in the copper can.  · I made sure that the water started with the same temperature with the same alcohol.  · I made sure that the height was the same from the water to the thermometer. Health and Safety  · Wear goggles  · Hide tie in the shirt  · Keep bags under the table Method I first got all the apparatus that I needed and set it up. I got a measuring cylinder and measured a 100 cm ³ of water and poured it in a copper can. Then I connected the copper can to the stand with a clamp. Then I would get a spirit lamp which is filled with alcohol and measure it. Then I would use a spirit to light it and put it under the copper can. Then I would heat and stir the water until the temperature has gone up another 10 degrees Celsius. I will then blow out the flame and put the cap on the burner quickly and reweigh the alcohol.

Extreme and Moderate Characters in Moliére’s Tartuffe Essay -- essays

Extreme and Moderate Characters in Tartuffe   Ã‚  Ã‚  Ã‚  Ã‚  In Molià ©re’s Tartuffe (Moirà © 1664), the reader is able to see a great contrast of Extreme and Moderate characters. Extreme characters being those who are seen as over the top, or very passionate people, and the moderate characters having a more calm and subtle approach to ideas. The extreme characters in this case would be Madam Pernelle, Orgon, Tartuffe, and Dorine. The moderate characters are seen as Cleante and Elmire.   Ã‚  Ã‚  Ã‚  Ã‚  One of the characters that obviously fall into the extreme character category would be that of Madam Pernelle. Madam Pernelle is an excellent example of an extreme character because of her sharp remarks, and the idea of telling people exactly what she thinks. From the very beginning of the play, the reader is able to identify how out spoken this character is when she begins to defend Tartuffe in the opening pages.. This is demonstrated when Madam Pernelle comments on a remark made by Dorine saying, â€Å"Girl, you talk to much, and I’m afraid / You’re far too saucy for a lady’s maid. / You push in everywhere and have your say† (I, I, 21)   Ã‚  Ã‚  Ã‚  Ã‚  Another example of an extreme character in Tartuffe would be the character of Dorine. Much like Madam Pernelle, Dorine is an outspoken individual who does not like to be argued or reasoned with. She is very adamant about her idea of Tartuffe, and will not be easily persuaded into thinking otherw...

Parallels Between Nora in “A Doll’s House” and Blanche in “Streetcar Named Desire”

Within the classic works of literature, there often exist parallels between characters, settings, themes, and the like.   An especially interesting example of parallels among characters exists between Nora in Ibsen’s â€Å"A Doll’s House† and Williams’ â€Å"A Streetcar Named Desire†.In this paper, the parallels between these characters will be presented, not only in the outward appearance and circumstances of both, but also in terms of common themes, symbolism, and more in order to provide a well rounded piece of research and evaluation of these complex protagonists.Nora and Blanche Superficially ComparedTo begin, Nora and Blanche will be compared in terms of their outward characteristics and environments so that a basis of comparison can be established on the most basic level, before more in-depth comparison can take place.Nora, in â€Å"A Doll’s House†, is presented by Ibsen on the surface as a vulnerable woman, dependent upon the assistance and approval of others, especially men.   Having led a sheltered life, Nora grows up in the care of her father, and immediately moves to the care of her husband upon her marriage, giving the reader the distinct impression that she is totally reliant upon the help of others, or more precisely, the help of male figures of authority (Drake).As a result of this fragility on her part, Nora becomes impulsive and materialistic as the work unfolds in the initial portions of it; however, the tantalizing suggestion exists that Nora uses a practiced vulnerability in order to ultimately manipulate the men in her life.   As the story reaches its climax, Nora emerges from her circumstances as a fully independent woman who rejects the idea that marriage and motherhood is necessary to validate her as a person (Ibsen).Blanche, as portrayed in Tennessee Williams’ â€Å"A Streetcar Named Desire† is also presented as somewhat vulnerable and reliant on others, but in differ ent ways.   Early in her life, Blanche leans on a man whom she believes will be her husband and take care of her, but ultimately, through a series of complicated situations including his confrontation of his own homosexuality, he takes his own life, leaving Blanche to her own devices (Bloom).In an effort to validate herself, Blanche becomes the caretaker for the elderly members of her family, watching each of them pass away one by one, and along with them, a piece of her dies as well.   Ultimately, Blanche finds herself seeking shelter and support from others when, as she loses her home and financial resources, she is forced to move into an apartment with another woman and man.Like Nora, Blanche initially seeks validation and protection from men, but in her case, the men are a series of strangers with whom she indulges in intimacy in a fruitless search for attention, protection and a sense of herself (Combs).   Ultimately, Blanche is forced to face the reality of her inner sel f, and like Nora, come to some hard decisions about who she has been, who she will become, and how all of this will interrelate.In comparing Nora and Blanche simply on the surface, we see two women who are seeking to find their way in the world so to speak, but more importantly, each is also trying to find out who they really are and also trying to find a sense of independence and validity despite trying circumstances.This being understood, there are several key themes that these women have in common; themes that are more abstract but important nonetheless.   They are identified and discussed as follows:Fantasy Versus RealityBoth Nora and Blanche find themselves in a struggle between fantasy and reality; initially, both women are lulled into the false fantasy world where men make them complete, validate their existence, and will help them to live happily ever after, as the classic fairy tale goes.However, as reality sets in, both women find that they ultimately need to define them selves on their own, and the actual reality is that we all find ourselves alone and should not rely on someone else to complete or validate our existence.   For Nora, reality comes in the form of her independence from marriage and motherhood, which allows her the luxury of full expression of her inner self.   For Blanche, reality comes in the form of the gravity of her promiscuity and the effect that it has had on others, as well as herself.LonelinessFor the entire action taking place around them, it is fair and accurate to assert that both Nora and Blanche are lonely in one sense or another.   While it is not the type of loneliness that comes from being totally alone, it is the type of loneliness that comes from not truly knowing anyone, including themselves.Nora realizes eventually that she is a stranger even to herself, and this leaves her feeling quite alone.   For Blanche, faced with the seemingly constant loss of loved ones through illness and death, she is eventually alone in the literal sense, being the sole survivor of her family.   Loneliness permeates both of these characters, and shapes them forever, for better or worse.DesireThe presence of romantic, emotional, and material desire is a common element to be found in both Nora and Blanche.   Desire is something that can be a positive motivator or a destructive force, and it manifests itself in both ways in the case of these characters, respectively.   In Nora’s case, desire first exists in terms of her desire to feel safe and protected by the men in her life, first her father and then her husband.At the conclusion of â€Å"A Doll’s House†, Nora has a desire to be independent and define herself, which she pursues.   Blanche, in â€Å"A Streetcar Named Desire†, has desire of the amorous nature, which burns so hotly that it almost consumes her in its intensity.   At the conclusion of Blanche’s saga, her desire for the love of a man is what brings her full circle in her life experiences.Constant ChangeThere is an old irony that says that the only constant in the world is change; in the case of these characters and works, this is definitely the case.   Change, for better or for worse, charts the course of Nora and Blanche throughout their respective stories.Nora goes through a wide variety of changes, as her domestic situation changes through marriage, and changes once again as she comes to the realization that she is actually her own woman and does not need approval from others to thrive.Blanche goes through the end of the â€Å"Old South† as her role models all fade into eternity and she must change all that she has known as her everyday life.   Both women change constantly and move forward with the action of their stories.The Male and Female DynamicThe dynamic between women and men is as old as time itself, and is a unifying theme in both â€Å"A Doll’s House† and â€Å"Streetcar Named Desire†.à ‚   Nora struggles with the issue of being subservient to a man and allowing him to shape her world, while Blanche seems to want to submit to a man in order to shape her world.   These differences are along the same line of thinking- that men and women, for better or worse, do define each other to a certain extent, but total submission is a different situation altogether.   Both women interact with men, and it influences their lives for better or worse.Closing ThoughtsOn a higher level than the literal, Nora and Blanche represent some of the most intricate nuances of womanhood.   In their comparison, an understanding of the human soul as well, has been achieved.Works CitedBloom, Harold, ed.

Canadian Politics Essay

Some historical theorists say that the dissimilarities between America and Canada are established in the Revolution of America, a subject that dominated most studies in the history of Canadian. With the creation of the US, the core founders of the US supported republicanism, refusing the Westminster structure of parliamentary democracy. Republicanism that inspired Americans pressured independence, an aversion to corruption, and innovation, counterbalanced by an apparent need for loyalty to public duty. Many Americans in planning a unique American path, freighted, and therefore refusing, a sturdy nation, which is central government. This paper looks into the different ways to which the Canadian political structures differs with those of the US. America and Canada are both governed under constitutions; Canada’s constitution is partly conventional and partly written, and that of the US fully codified. The ultimate interpreter of the constitutions of both countries is their own supreme courts. Nevertheless, the High Court of the US has a more stretched history of constitutional implementation than the High Court of Canada. Canada’s Constitution contains of Acts of both the legislature of the UK and the National Assembly of Canada, but because of the Canada’s federalism, several Acts of regional parliaments like the lawmaking Assembly of Ontario. The Constitution was altered in 1982, at which the Canadian Charter of Rights, Freedoms and amending formulas were included. The other one basic concept on these differences is the dissimilarity between the US congressional system and the Canadian parliamentary system. More differences occur from the legal/political perception of division of powers and the authority of the head of state. The President of the US is the head of government and head of state, while Canada’s Prime Minister is not head state but only head of government (Charlton, 1998). Another distinction is the Governor General and his or her cabinet ministers- also playing roles as legislators, represent the combination of power in Canada’s system, with the part of the monarch. Ministers of the crown are normally directly elected by their respective electorates known as ridings who advise the monarch or the Vice Governor General on how to practice his Crown authority and as Members of the legislature in the Canadian House of Commons. Even though neither the Governor general nor monarchs are lawfully required to select his or her cabinet Members from the House. This indicates those in charge of executive duties also contribute as legislators in the policy discussions and lawmaking process features of their duties as Members of National Assembly. By contrast, the US president has no official duty as a legislator, but only implementing and enforcing laws passed by Congress. The President of the US contributes in only informal, occasional, gatherings with Senators and Representatives. Only formally, addresses once in a year in the two term of his Presidency the gathered houses of the Congress, the Cabinet, and the Justices of the High Court of the US (James, 2004). The checks and balances in Canada are very opposite from those in the US, it can be debated that within Canada that the Prime Minister has additional authority than the US President. Canada’s executive and legislative branch draw from each other, the viceroy hardly uses their powers without the consent of the Prime Minister. This only occurs from situations brought on by constitutional crisis. To ensure the firmness of government, the Governor must always select for his Prime Minister a member who has the biggest group of followers in the Canadian Common House. The Prime Minister must resign or order the General to call for an emergency election or be forced out by the governor general if a big number of the house vote against the government on serious matters of the country. The Prime Minister of a marginalized government is in a much dangerous situation than any United States president, which his presidency term is secured by the law. Often times of cohabitation are also there in the US known as divided government. Happens when different group than the White house directs congress. The President has incomplete control over the members of the House and must regularly make deals for there support. This leads to a stalemate that greatly slows down the law-making process (Charlton, 1998). It is known that the lack of individual identity which characterizes the resulting efficacy of the combined policy activity of the individuals participating in, and influencing the progression of, the US separation-of-powers system in contrast to the personal identity that characterizes the resulting efficacy of the aggregate policy activity of individuals participating in, and influencing the progression of, the Canadian fusion-of-powers system that truly makes this distinction meaningful. An example (putting federalism aside, arguendo) would be the one political actor in Canada responsible for motivating national defense policy decisions for Canada, the Minister of National Defense, contrasted with three(the Secretary of Defense, and the two chairs of the Senate Committee on Armed Services and House Committee on Armed Services) sometimes adverse political actors responsible for the direction of national defense policy Centralization of power in Canada has some benefits and legal responsibility when matched with the United State system. A good line of authority/power showing to whom the government is accountable for any particular duty Unlike the U. S. (James, 2004). There is also the issue of political parties whereby the Canadian House of Commons has seats for four political parties while US has only two political parties in Congress. Both Canada and the US use first post system to elect their representatives. This type of a system can sometimes exaggerate regional interests and disparities, e. g. Dixiecrats and Quebec of the southern. The meltdown of progressive Conservation party and the rise Quebecois party changed the political field in Canada. At the past only two parties dominated federal politics like the US, these parties were the Progressive Conservatives and the liberals, the Liberal held power for most of the 20th century until they were known as Canada’s natural governing party. Different from the US, Canadian third parties have always been able to get Members of parliament elected into the National Assembly since 1921, at times succeeding one of the two main parties as Her Majesty’s Loyal Opposition or forming casual coalition governments (Paul, 1992), In my opinion there are great differences regarding the way political cultures in Canada and the US. This is clearly shown on how the different political institutions in both countries are being managed and the structure through which these institutions are developed. Therefore, it would be appropriate for one to say that the Canadian political culture is not and has never been Americanized even though there are some aspects of similarity in other government structures References Charlton, Barker (1998).

Cache coherence Term Paper Example | Topics and Well Written Essays - 2250 words

Cache coherence - Term Paper Example The problem of cache coherence in hardware is reduced in today’s microprocessors through the implementation of various cache coherence protocols. This article reviews literature on cache coherence with particular attention to cache coherence problem, and the protocols-both hardware and software that have been proposed to solve it. Most importantly, it identifies a specific problem associated with cache coherence and proposes a novel solution. Keywords: microprocessor, latency, cache coherence, bandwidth, multiprocessor, cache coherence protocol, shared memory, multicore processor I. Introduction Currently, there is undeniable interest in the computer architecture domain with regard to shared-memory multiprocessors. Often, proposed multiprocessor designs include a reserved cache for each processor within the system. This, in turn, results in the cache coherence problem (Cheng, Carter, & Dai, 2007). This situation, in which several caches are allowed to have simultaneous copies of a certain memory location, requires that a certain memory location be in place. This is to make sure that when the contents of that particular memory location are changed, there needs to be a mechanism that ensures all copies remain unchanged. Consequently, some systems employ a software mechanism to ensure multiple copies do not occur. This it achieved by labeling shared blocks so that they are not cached (Chang & Sohi, 2006). Additionally, task data in all caches are prohibited or restricted from migration. Alternatively, all blocks may be allowed to be cached by all processors and to depend on a cache coherence protocol to be responsible of ensuring that there is consistency. Various such protocols have been proposed, designed and/or described with some ideal for shared-bus and others specifically suitable for a general-purpose interconnection network. There is a substantial difference between shared-bus protocols and general network protocols. Firstly, share-bus protocols dep end on every cache controller monitoring the bus transactions of all the other processors within the system and take appropriate action to ensure consistency is maintained. Secondly, each block’s state within the system is encoded in a distributed manner among all other cache controllers. As such, the cache controllers are able to monitor the traffic of the bus for the purposes of coherence; these are referred to as snooping cache controllers (Kurian et al., 2010). Recently, many studies and researches have been conducted and have mainly focused on shared-memory multiprocessors. They are common mainly because of their simple programming model, which means that they are simple to implement. Normally, address space is shared among all multiprocessors. This enables them to communicate to one another via a solitary address space. As had been earlier noted, a system with cache coherence results in the event that there is same cache block within multiple caches (Stenstrom, 1990). W hen such a scenario occurs, it does not affect the read process; however, in the event that a processor, for writes, writes to a single location, the resulting change must be updated to all caches. Therefore, cache coherence, according to (Archibald & Baer, 1986), refers to all caches having consistence data in the event of data write.

Nigeria and Oil Extraction Essay Example | Topics and Well Written Essays - 2000 words

Nigeria and Oil Extraction - Essay Example Oil industry forms a major part of the export sector of Nigeria. However, the oil drilling and oil exploration has lead to massive environmental problems, such as water pollution, land degradation and breakdown of ecosystem. These issues have created further social problems in the lives of Nigerians. It seems that Nigerians are paying a huge price for economic development. Oil forms a pertinent part of the exports of the African country, Nigeria. In fact, much of the development, which started in the 1950s in this country, has been attributed to the revenue obtained from the oil industry. Moreover, future advancement in Nigeria depends largely on this industry. Nigeria comes second to the leading African nations, exporting oil. Since the discovery of oil in 1959, the country has largely become independent on this commodity for its foreign exchange reserves. Nigeria has improved economically and socially, since this has led to better infrastructure facilities, and a better trade balan ce. Nigeria is bound to progress in every occupation, because it remains one of the nations having huge amount of oil reserves, which remains the most prized commodity. Therefore, oil exploration and drilling should have profound impacts on the lives of Nigerians, which advances their lifestyle. This could mean in terms of better living conditions, education, better agriculture, better environment and availability of food (Emiri, Deinduomo, pp.349, year). However, this has not been the case, when it comes to Nigeria. Nigeria remains one of the Third World Countries, which is crippled by the same problems such countries face. One of the common problems faced by Third World Countries includes the rapid environment degradation. Environmental degradation has been advanced by the oil industry, because of the drilling impacts. The paper largely focuses on the different environmental impacts that the oil industry has created. It has become an issue of immense concern, especially in the rec ent decades. Environmental degradation has gotten quite out of hand. This can be proved by the fact that the Millennium Development Goals, which had to be completed by various countries by the year 2012, includes the issue of environmental management. Environmental management includes areas such as the protection and the sustainable use of the elements of the environment. It also includes the reversal of those environmental problems, which humans have created (Child Development, n.p). However, Nigeria has remained far behind in this goal. Environmental degradation has multiplied; because of the increased oil, drilling that has been occurring since the past few decades. Nevertheless, that does not signify or assume that there remains no environmental awareness in Nigeria. The negative environmental effects of oil operations have largely been studied and documented by van Dessel, who used to be the environmental studies head of Shell in Nigeria. He found out that many of the environme ntal problems stem from oil spills, gas flares, oil and other waste, drilling and even during surveys. Seismic surveys create many problems, such as the cutting of lines that adversely affect the mangroves forestation. The whole ecosystem gets disturbed in this way. Therefore, one such simple example shows the numerous environmental effects of oil drilling (Frynas, pp. 158). The environmental impact has been significant particularly in one area, which includes the Niger Delta region. This region forms part of history in the way that the first oil exploration was conducted in this area in 1956. At the time of discovery, some 5000 barrels of oil were produced every day. However, now the production has extended to such a large
