tion, we derive an expression for the Gibbs free energy depending on the number of particles, temperature, pressure, and on several typical values of enthalpy. The limiting cases correspond to the Debye theory for heat capacity of solids and to the chemical potential of ideal gas. Note that in the latter case, the mean volume per particle tends at T 0 to its value in the condensed state. This equation of state is in good agreement with the experimental data.
