New distributions in thermodynamics

Resumo

A model of the equation of state for classical gases consisting of nonpolar molecules is constructed under the assumption that the spinodal, critical isochore, and second virial coefficients of the gas have been set. The corresponding thermodynamic distributions are determined. It is shown that the isotherms constructed in the framework of the proposed model coincide with the isotherms of the van der Waals model obtained on a different basis.
