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

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

The domain of prosecutors has been extended to provide greater authority. An example of domain expansion of the prosecutors is improving police-prosecutors relationships. Truthfully‚ police officers and prosecutors are looked at as the bad guys in the eyes of the public. They are both to serve justice‚ even though they have different perspectives on the law. For example‚ the police officers consider a case to be closed when the suspect is arrest‚ but the prosecutor needs obtain more information and

Modern Human Expansion Archaeology 201 November 23‚ 11 Modern Human Expansion Modern human expansion from Africa began 70‚000-85‚000 thousand years ago‚ but recent discoveries have found that they could have exited as early as 125‚000 years ago. Many factors lead to the beginning of the African exodus of the modern human population. The most prominent factors involved with their rapid expansion are the drastic climate changes in that area. As well as that‚ a diverse diet rich in seafood

Manifest Destiny was a movement started by journalist John O’Sullivan to state his opinion that expansion was a part of the "the great experiment of liberty." This promoted the great Westward expansion. The Westward Expansion highlights 3 of the largest characteristics of the American spirit‚ the desire for freedom‚ the need of wealth‚ and the willing to sacrifice for others.

1. Nomadic expansion has affected history in many ways. When nomadic groups expand they take over different peoples sometimes even destroying empires‚ like in the case of Assyria and Harappa. Expansions have also called major movements in population. When an empire flourishes more people move to the empire than move away from it making it a center of population increase. They have also spread technology; especially things that help in warfare‚ established trade among empires‚ and helped get world

Expansion Without Religion Religion played a huge role in westward expansion‚ but without the colonists’ theological roots‚ expansion most likely would have remained the primary goal for immigrants‚ as this was still a period of abundance‚ and the fact that the immigrants adapted their theology to justify their murderous actions means that they probably would have just found another way to condone their ways. Religion played a very important part in developing the United States into what it has

Expansion of the Panama Canal & Heartland Barge The Panama Canal enables the ships sailing from the Pacific Ocean to the Atlantic Ocean (and vice versa) to save time and fuel by avoiding the travel around the tip of South America. The savings in time equal half of the time previously taken by ships to do the same. The size of ships that are used in shipping containers has drastically increased due to the container revolution. To enable the new and bigger ships such as Maersk Triple E Class to
