The clausiusclapeyron equation in its most common form is used to determine the gradient of phase transition lines on a pressuretemperature plot. For the boundary between solid and liquid phases, the entropy of transition. To derive the clausiusclapeyron equation we look at how pressure and volume vary with each other as a phase change. In order to plot the clausiusclapeyron relation and to compare it against experimentally measured vapor pressure curves, we need to integrate equation. H trs t this is because on the phase boundary the two phases are in equilibrium, so the heat transfer, which is equal to the enthalpy.
