latent heat

n.
The quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water to steam, at constant temperature and pressure. Also called heat of transformation.

latent heat

n
(General Physics) (no longer in technical usage) the heat evolved or absorbed by unit mass (specific latent heat) or unit amount of substance (molar latent heat) when it changes phase without change of temperature

la′tent heat′


n.
heat absorbed or radiated during a change of phase at constant temperature and pressure.

The quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water changing to ice, at constant temperature and pressure.

latent heat

1. The quantity of heat which is absorbed or released by a substance during a change of state (fusion or vaporization) at constant temperature.
2. Heat released or absorbed when a substance changes state without a change in temperature.
