Interacting Classical Gas
摘要
The assumption that the molecules of a gas do not interact though models a number of systems, there are situations of practical interest which the assumption in question leaves out. For example, the phenomenon of phase transition, discussed in Chap. 11 , can not be explained by the equation of state of a non-interacting gas. In this chapter, we introduce a systematic way of treating interaction between molecules of a classical gas by expressing its equation of state as an expansion in terms of its number density.
