Thermodynamics Section Review 9A: 1. Scientists believed that the caloric was a material but mainly that it was an invisible fluid consisting of self-repelling particles. Two examples include how gases expand according to Newton’s laws‚ and determining the speed of sound in air. 2. The first person to successfully challenge the caloric theory was Benjamin Thompson. Benjamin observed that a dull boring bit could generate more hat than needed to melt the entire cannon barrel. 3. The significance

Thermodynamic Investigation of the Joule-Thompson Effect and Coefficient Determination for Helium and Carbon Dioxide Niki Spadaro‚ Megan Cheney‚ and Jake Lambeth University of North Florida‚ CHM4410C Fall 2010 The Joule-Thomson coefficient explains the behavior of any real gas when changes in intensive properties‚ such as temperature and pressure‚ occur. The coefficients for helium and carbon dioxide were determined using a Joule-Thomson apparatus that created constant enthalpy within the

Another industry related to the second law of thermodynamics is the air-conditioner. As the weather in this country‚ Malaysia is always hot and humid‚ air-conditioners are used to cool down the surrounding inside the house. In fact‚ the concept of air-conditioner is one of the applications of the second law of thermodynamics which stated that for any process occurring in a closed system‚ the entropy increases for an irreversible system and remains constant for a reversible system‚ but never decreases

Course paper in Philosophy of Science and Ethics Title: The relevance of Statistics and Probability for the study of the thermodynamics properties (The Maxwell-Boltzmann Theory) Abstract There are many philosophical debates as to the appropriateness of the use of statistics and probability as scientific research measures. Many renowned philosophers believe that since scientific investigation aims at the ultimate goal of presenting truth about the observations and processes in our universe
