Abstract:
In contrast to the supercritical region where the isotherms ideally coincide with the isotherms of the van der Waals model, we introduce an additional condition for the Hartley entropy to attain maximum on the spinodal in the subcritical region. To determine the parameters of the distribution and isotherms, we use spinodal equation.
Keywords:Gibbs paradox, Boltzmann statistics, parastatistics, van der Waals model, Bose–Einstein statistics, spinodal.
