Water has a heat of vaporization of 44.0 kJ/mol while the chemical diethyl ether has a heat of vaporization of 27.1 kJ/mol.This shows that one mole of water would vaporize more easily than would one mole of diethyl ether.

Question

Quizplus · Accepted Answer

The heat of vaporization is the amount of energy required to convert one mole of a liquid into its vapor phase without changing its temperature. A higher heat of vaporization means that more energy is required for the substance to vaporize. Therefore, since water has a higher heat of vaporization than diethyl ether, it means that water requires more energy to vaporize than diethyl ether, not that it vaporizes more easily.
