heat of vaporization

noun

, Physics.

1. the heat absorbed per unit mass of a given material at its boiling point that completely converts the material to a gas at the same temperature: equal to the heat of condensation.

heat of vaporization

1. The amount of heat required to convert a liquid into a gas at constant temperature and pressure. A gas releases the same amount of heat when it becomes liquid.
2. Compare heat of fusion

Example Sentences

This “heat of vaporization” energy is known for many materials, but for a person we can focus directly on their water.

From Scientific American

The heat absorbed when the volume is increased corresponds with the latent heat of vaporization.

From Project Gutenberg

Griffiths subsequently applied the same method to the measurement of the specific heat of aniline, and the latent heat of vaporization of benzene and water.

From Project Gutenberg

On the other hand, it must be remembered that, as in the case of water, the lower the temperature of the evaporating liquid, the higher is the heat of vaporization.

From Project Gutenberg

Very careful experiments show the exact heat of vaporization to be 536.1 calories.
