### Formula

DeltaHvap

the molar enthalpy of vaporization

T1

temperautre at one point

P1

corresponding vapor pressure at temperature T1

T2

temperature at another point

P2

corresponding vapor pressure at temperature T2

DeltaHvap

the molar enthalpy of vaporization

T1

temperautre at one point

P1

corresponding vapor pressure at temperature T1

T2

temperature at another point

P2

corresponding vapor pressure at temperature T2

The Clausius-Clapeyron equation for the liquid-vapor boundary may be used in either of two equivalent forms. If the corresponding temperature and pressure is known at two points, the enthalpy of vaporization can be determined.
