The enthalpy of vaporization, also known as the heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressure at which that transformation takes place.
Importance
Water's high heat of vaporization is important because it helps to moderate the temperature of the ecosystem. When water goes through the water cycle (evaporation, condensation, precipitation), at the stage of precipitation, heat is released, and rain falls.
Application
Two practical applications of heats of vaporization are distillations and vapor pressure: ... The concentration of a gas is given by its vapor pressure. Knowledge of the heat of vaporization permits the control of vapor pressure by setting the temperature of the liquid being vaporized.
