EXPERIMENT 1: ISENTROPIC EXPANSION PROCESS Objectives: 1) To demonstrate the isentropic expansion process. Introduction: In thermodynamics‚ an isentropic process is a process in which the process takes place from initiation to completion without an increase or decrease in the entropy of the system. One example of a process that approaches being isentropic are the rapid depressurization of gas in a cylinder. The entropy of the system remains in constant. Entropy is a type of energy

If expansion is the true American ideal‚ the western frontier is the impetus and manifest destiny is the justification. This is Americanism at its purest: expansion across and improvement of the lands. The frontier represents an escape from urban life and directly supports Jefferson’s agrarian vision for the American economy. The agrarian myth holds that the most desirable type of society is one with an economy strongly rooted in farming. The myth suggests that a farming lifestyle is a pure one

Linear Thermal Expansion The term thermal expansion refers to the increase in size of an object as that object is heated. With relatively few exceptions‚ all objects expand when they are heated and contract when they are cooled. Perhaps the most important exception to this rule is water. Water contracts as it cools from its boiling point to about 39.2°F (4°C). At that point‚ it begins to expand as it cools further to its freezing point. This unusual effect explains the fact that ice is less dense

Coefficient of Linear Expansion Introduction With few exceptions materials expand somewhat when heated through a temperature range that does not produce a change in phase (i.e. melting‚ freezing‚ boiling etc.). The added heat increases the average amplitude of vibration of the atoms in the material‚ which increases the average separation between the atoms. Although this effect is small‚ it is very important in any application that involves using different materials in an environment where they

Thomas Jefferson was a man who was against slavery and believed in freedom. His thoughts of slavery was it was a destruction to America . Jefferson also saw slavery as an abolishment of the right to personal liberty. During the time of the American Revolution‚ Thomas Jefferson was very involved in the legislation in hopes it would result in the abolition of slavery. As Jefferson began to abolition slavery‚ the population of slaves began to rise. Instead slavery became more widespread and profitable

Reform Movements and the Expansion of Democratic Ideals The years between 1825 and 1850 marked the reform movement era that spread democratic ideals the country was founded on. Throughout the fights for equal rights‚ freedom of religion‚ and institutional improvements‚ citizens leaned more towards having a democratically governed country. This era was the time when everyone fought for the same rights white men had. Colonial women‚ who were expected to endure their husband’s abuse and alcoholism

The Western expansion of the United States from 1860-1890 was a domino effect. Numerous factors came in to play which built upon themselves to cause America to grow and move west‚ but the biggest factor was the transcontinental railroad. As the railroads were put in‚ lands improved‚ trade increased‚ cities grew and territories became states. With every passing decade‚ clear growth could be seen in all aspects of life. The railroad took seven years to build between two different companies‚ but
