The Thermos and Thermodynamics Physics around Campus Phoebe Seaver Physics 102 Spring 2017 In the photo, we see two coffee cups, one that is in an insulated thermos with a lid, and one that is a regular mug open to the air, on a college student’s desk at home during their finals studying. It is well known that as coffee sits in any container, it cools down towards room temperature, making it less tasty to drink once it gets lukewarm or even room temperature. However, if it is too hot, it can burn the drinkers tongue and throat, which is incredibly painful, speaking from experience. The rate at which coffee cools may not seem like a science, but in fact, this plays into the laws of thermodynamics that are present in†¦show more content†¦Often, energy is lost to the surroundings, and not directly transferred from one object to the other. However, a perfect thermos would prevent any heat from leaking out or in. Energy in the form of heat can flow between materials inside the thermos to the extent that they have different temperatures; for example, between ice cubes and warm coffee. The transfer of energy continues until a common temperature is reached at thermal equilibrium (Cutnell 2014). Thermal equilibrium occurs when there is no heat flow between two materials, making them essentially the same temperature. This is why the coffee continues to cool down the longer it is exposed to the air, because heat exchange is occurring, and the liquid is cooling down from its original warmth to be more like the room that is it in, as the room has less heat. This is why a thermos causes the coffee to cool down slower, because the thermos provides insulation against the exchange of heat from the outside. The extra insulating layer is actually a vacuum, or absence of air, formed during the construction of the thermos. The best insulator possible is a vacuum, because there s no air. If there s no air to transfer heat, then the heat is retained where it is (wonderopolis.org). The equation for Specific Heat: .

Political Conservatism and the Role of Religion

Quite often, those on the left of the political spectrum dismiss political conservative ideology as the product of religious fervor. At first blush, this makes sense. After all, the conservative movement is populated by people of faith. Christians, Evangelicals, and Catholics tend to embrace the key aspects of conservatism, which include limited government, fiscal discipline, free enterprise, a strong national defense, and traditional family values. This is why many conservative Christians side with Republicanism politically. The Republican Party is most associated with championing these conservative values. Members of the Jewish faith, on the other hand, tend to drift toward the Democratic party because history supports it, not because of a particular ideology. According to author and essayist Edward S. Shapiro in American Conservatism: An Encyclopedia, most Jews are descendants of central and Eastern Europe, whose liberal parties -- in contrast to right-wing opponents -- favored Jewish emancipation and the lifting of economic and social restrictions on Jews. As a result, Jews looked to the Left for protection. Along with the rest of their traditions, Jews inherited a left-wing bias after emigrating to the United States, Shapiro says. Russell Kirk, in his book, The Conservative Mind, writes that, with the exception of antisemitism, The traditions of race and religion, the Jewish devotion to family, old usage, and spiritual continuity all incline the Jew toward conservatism. Shapiro says Jewish affinity for the left was cemented in the 1930s when Jews enthusiastically supported Franklin D. Roosevelts New Deal. They believed that the New Deal had succeeded in alleviating the social and economic conditions in which antisemitism flourished and, in the election of 1936, Jews supported Roosevelt by a ratio of nearly 9 to 1. While its fair to say that most conservatives use faith as a guiding principle, most try to keep it out of political discourse, recognizing it as something intensely personal. Conservatives often will say that the Constitution guarantees its citizens freedom of religion, not freedom from religion. In fact, there is plenty of historical evidence that proves, despite Thomas Jeffersons famous quote about a wall of separation between church and state, the Founding Fathers expected religion and religious groups to play an important role in the development of the nation. The religion clauses of the First Amendment guarantee the free exercise of religion, while at the same time protecting the nations citizens from religious oppression. The religion clauses also ensure that the federal government cannot be overtaken by one particular religious group because Congress cannot legislate one way or another on an establishment of religion. This precludes a national religion but also prevents the government from interfering with religions of any kind. For contemporary conservatives, the rule of thumb is that practicing faith publicly is reasonable, but proselytizing in public is not.

John Marshall Free Essays

John Marshall, whose most notable political role of Chief Justice of the United States, played a major role in defining the American legal system, he was also known as one of the best Chief Justices that ever lived. For 34 years as Chief Justice, Marshall made significant contributions to the development of the U. S. We will write a custom essay sample on John Marshall or any similar topic only for you Order Now Constitution through his high profile Supreme Court cases, such as Marbury v. Madison, McCulloch v. Maryland, Cohen’s v. Virginia, and Gibbons v. Ogden. These Supreme Court cases and others were approaches to help bring more federal structure to the U. S. Constitution. Marshall’s thirst for political knowledge at an early age, his contribution the judicial system, and dedication to political reform make him one of the most influential figures in American history. Early Life John Marshall, one of fifteen children, was born on September 24, 1755 in a log cabin in rural Germantown, Virgina. His parents were Thomas and Mary Marshall, who had significant status among the citizens of Germantown. Although Marshall’s parents were not formally educated, they ensured their children had a good, quality education. Marshall was homeschooled and often supplemented his reading from books in George Washington’s library. Marshall’s father and George Washington worked together as surveyors and became close friends. Washington would later become one of Marshall’s greatest heroes. Desiring their son to become a lawyer, Thomas and Mary sent Marshall to William and Mary College where he spent several weeks listening to George Wythe’s lectures on law, which was Marshall’s only means of formal education. At the age of 25, Marshall left William and Mary College and pursued a lawyer’s position in Germantown, where he later met and married his wife of 49 years, Mary Willis Ambler. Together, they had ten children, with only six living to see adulthood (McGill, 2005). Chief Justice Chief Justice John Marshall served in the Supreme Court from 1801-1835. He was the fourth Chief Justice appointed by President John Adams (Smith, 1996). Marshall was known as one of the greatest chief justices in judicial history. While head of court, Marshall helped establish foundations for the Supreme Court and the constitutional supremacy. Alexander M. Bickel, a sophisticated, constitutional scholar stated that John Marshall was one of the greatest justices due to his decision in the Marbury v. Madison case. Although Marshall is known for many other cases throughout judicial history, including McCulloch v. Maryland, Cohen’s v. Virginia, and Gibbons v. Ogde, the high profile case, Marbury v. Madison, became one of Marshall’s most significant cases and one that established him as one of the greatest supreme court justices who ever lived (Wood, 1997). Marbury V. Madison In Marbury V. Madison, Marshall worked the Judiciary’s claim to apply the law of the constitution exactly the way that courts interpret common law and statues in their role of legal disputes. Marshall was instrumental in laying down the foundation for the rise of the Judiciary. Their goal was to make the Judiciary as one of the top three capital powers of the government. Marshall stated that the constitution was â€Å"a rule for the government of courts, as well as of his legislature†. As he made the issue known, judges could not ignore it. They were duty bound to enforce it by disallowing laws offensive to the constitution. At the time, many Americans had no trouble thinking of constitutions as law but not the kind of law that would be operated in the court system, but John Marshall stated towards the court system, by applying his methods of statutory interpretation to the constitution, he legalized it. He made it amenable to routine exposition and makes it happen. Marshall knew the Judiciary system would always be one of the weakest branches; its effectiveness depended on gaining the agreements of the legislative, executive branches, and of the people. The power that the Supreme Court would enjoy is the ability to persuade the people. Marshall was perfect for the job, and he greatly enhanced that power by his ability of persuasions. The American’s didn’t know anything about the constitution, but Marshall enhanced the knowledge pertaining to the constitution (Hobson, 2002). It is no doubt that John Marshall has made tremendous contributions to the judicial system. His thirst for knowledge at a young age and his political leadership has provided significant contributions to political society. It has been over two-hundred years since Marshall’s appointment; however, the Supreme Court still continues to honor him and his works. Marshall left a legacy that will be admired and written about by political generations to come. Through his works, Marshall helped define our country to what it is today as supported by political author, Jean Edward Smith who stated, â€Å"if George Washington found the country, John Marshall defined it† (Smith, 1996).
