Latent heat is the heat absorbed or released during a phase transition (like melting, freezing, vaporization, condensation, sublimation) that occurs at a constant temperature. 'Latent' means hidden, as the heat transfer does not result in a temperature change during the process.
The amount of heat required to change a liquid to gaseous state without any change in temperature is known as
