Clapeyron-Clausius Equation

The differential equation relating pressure to temperature in a system in which two phases of a substance are in equilibrium. dp/dT = L/(T Missing Image:IMG src="c_files/deltabg.gif"V) where p is pressure; T is temperature; L is the latent heat of the phase change; and Missing Image:IMG src="c_files/deltabg.gif"V is the difference in volume of the phases. Also called Clapeyron equation, Clausius-Clapeyron equation.
