摘要
The van der Waals model of a dense fluid is represented by a simple partition function. It is shown that this function, coupled with a choice of plausible ad hoc assumptions, leads to any one of several well-known equations of state including the empirically successful equation of Redlich and Kwong. A modern version of the van der Waals equation is obtained by a perturbation on the hard-sphere equation of state of Carnahan and Starling; the effect of attractive forces is found from a corresponding-states representation of the observed properties of argon. Finally, it is shown that when Prigogine's simplifying assumptions are made about the effect of rotational and vibrational degrees of freedom, the simple partition function can be used to derive a useful treatment of liquid polymers and other complex liquids.
