G as a function of P at constant T for liquid and solid phases. As we can see from the fundamental equation, dG = VdP - SdT, the free energy of a phase increases with pressure: If the two phases have different molar volumes

Show that the difference in volume across a first-order phase boundary is givenby ∆V = - ∆F/P.
