Document Summary
Form a sound foundation for the development of the principles of thermodynamics. Review the metric si and the english unit systems. Explain the basic concepts of thermodynamics such as system, state, equilibrium, process, and cycle. Review concepts of temperature, temperature scales, pressure, and absolute and gage pressure. The name thermodynamics stems from the greek words therme (heat)and dynamis (power). During an interaction, energy can change from one form to another but the total amount of energy remains constant. The first law of thermodynamics: an expression of the conservation of energy principle. The second law of thermodynamics: it asserts that energy has quality as well as quantity, and actual processes occur in the direction of decreasing quality of energy. Classical thermodynamics: a macroscopic approach to the study of thermodynamics that does not require a knowledge of the behavior of individual particles. It provides a direct and easy way to the solution of engineering problems and it is used in this text.
