What is Enthalpy of vaporization?

The enthalpy of vaporization is a function of the pressure at which that transformation takes place. The enthalpy of vaporization is often quoted for the normal boiling temperature of the substance. Although tabulated values are usually corrected to 298 K, that correction is often smaller than the uncertainty in the measured value.
It is equal to the increased internal energy of the vapor phase compared with the liquid phase, plus the work done against ambient pressure.
