Abstract

The used simple equation of state formula contains three temperature dependent parameters viz.: Second virial
coefficient, an effective hard convex bodies (HCB’S) diameter, and scaling factor for pair distribution function
at contact. All the parameters can be calculated from the intermolecular potential of HCB’S, and hence the
thermodynamic properties such as Joule-Thomson inversion curve, bulk modulus, and isobaric expansivity etc.,
are calculated. The agreement of these calculated data with experimental data is quite good.
