The vaporization of a liquid occurs with heat absorption. To determine the enthalpy of vaporization, a known mass of the liquid which is to be investigated is vaporized in a special vaporization vessel in a current of air. The quantity of heat absorbed, which corresponds to the enthalpy of vaporization, can be calorimetrically determined.
