### What is Meant by the Clausius Clapeyron Equation?

Clausius Clapeyron equation is used to determine the vapour pressure at any other temperature if the vapour pressure and the enthalpy of vaporization at some temperature are known. We know that the vapourization curve for most of the liquids has the same curve. But when the temperature increases, the vapour pressure steadily increases.
