Here we discuss how to integrate the Clapeyron Equation along a liquid-vapor phase boundary. The result is the Clausius-Clapeyron Equation, which gives the pressure of the liquid-vapor phase boundary curve. We also note that the same considerations can be applied to get the pressure of the solid-vapor phase boundary curve, with enthalpy of sublimation substituting for enthalpy of vaporization in the resulting expression.
