Abstract:
An analytical equation of state was applied to calculate the thermodynamic properties for argon.The equation of state is that of Song and Mason. It is based on a statistical-mechanical perturbationtheory of the hard convex bodies and can be written as fifth-order polynomial in the density. Thereexist three temperature-dependent parameters: the second virial coefficient, an effective molecularvolume, and a scaling factor for the average contact pair distribution function of hard convexbodies. We used Lennard-Jones (۱۲-۶) potential for calculation of temperature-dependentparameters. The equation of state has been applied to calculate thermodynamic properties includingthe vapor pressure curve, the compressibility factor, fugacity coefficient for argon. The agreementwith experiment is good.
