[...]... Many countries have already banned the production of some of these compounds, and the search for improved replacement fluids continues These are only some of the many environmental problems caused by our efforts to produce goods and effects intended to improve our way of life During our study of thermodynamics, which is the science of the conversion of energy from one form to another, we must continue... excellent definition of thermodynamics is that it is the science of energy and entropy Since we have not yet defined these terms, an alternate definition in already familiar terms is: Thermodynamics is the science that deals with heat and work and those properties of substances that bear a relation to heat and work As with all sciences, the basis of thermodynamics is experimental observation In thermodynamics. .. first, second, and third laws of thermodynamics In addition to these laws, the zeroth law of thermodynamics, which in the logical development of thermodynamics precedes the first law, has been set forth In the chapters that follow, we will present these laws and the thermodynamic properties related to these laws and apply them to a number of representative examples The objective of the student should be... both chemical processing and cryogenics, thermodynamics is basic to an understanding of many phenomena and to the design and development of processes and equipment Air separation plants of many different designs have been developed Consider Fig 1.9, a simplified sketch of a type of plant that is frequently used Air from the atmosphere is compressed to a pressure of 2 to 3 MPa (20 to 30 times normal atmospheric... fuel tanks occupy the largest part of the volume of a rocket, and the range and payload of a rocket are determined largely by the amount of oxidizer and fuel that can be carried Many different fuels and oxidizers have been considered and tested, and much effort has gone into the development of fuels and oxidizers that will give a higher thrust per unit mass rate of flow of reactants Liquid oxygen is frequently... 4.3 Work Done at the Moving Boundary of a Simple Compressible System, 93 4.4 Other Systems that Involve Work, 102 4.5 Concluding Remarks Regarding Work, 104 4.6 Definition of Heat, 106 4.7 Heat Transfer Modes, 107 4.8 Comparison of Heat and Work, 109 4.9 Engineering Applications, 110 Summary, 113 Problems, 114 5 127 THE FIRST LAW OF THERMODYNAMICS 5.1 The First Law of Thermodynamics for a Control Mass...
