What is Clausius- Clapeyron Equation ?

The vaporization curves of most liquids have similar shapes. The vapor pressure steadily increase as the temperature increases.
If P1 and P2 are the vapor pressures at two temperatures T1 and T2, then a simple relationship known as the Clausius- Clapeyron Equation can be formed which allows us to estimate the vapor pressure at another temperature, if the vapor pressure is known at some temperature, and if the enthalpy of vaporization is known.
