ABSTRACT
Thus far frequent use has been made of the so-called ideal gas to illustrate the nature of changes in the thermodynamic state of a system. In this chapter the behavior of real gases is compared with ideal behavior, and the differences between the two are sought in the atomic or molecular properties of real gases. Although knowledge of the physical properties of a real gas is not required in a thermodynamic examination of the gas, an appreciation of the origin of physical properties provides a better understanding of the thermodynamic behavior.
