... It is seen from Fig. 3 that for solids or liquids, the change in volume with pressure is small, so V can be treated as a constant and the integral can be considered approximately as ≈ V∆p. Since at normal pressure the value of V∆p is small, we can suppose that the Gibbs energies of solids and liquid ...
