Latent Heat

When a substance adjustments phase, this is it is going from both a strong to a liquid or liquid to gas, the strength, calls for strength to do so. The potential energy withinside the interatomic forces among molecules desires to be conquered with the aid of using the kinetic strength of the movement of the particles earlier than the substance can change phase.

Latent Heat of Fusion and Vaporization

The strength required to extrude the section of a substance is referred to as latent heat. The phrase latent means were hidden. When the phase extrudes is from strong to liquid we ought to use the latent warmth of fusion, and whilst the phase extrude is from liquid to a gas, we ought to use the latent warmth of vaporization.

To initiate a phase change and whole it, a little energy withinside the form of heat is required. This heat is referred to as latent heat. Thus all of the energy provided all through this phase may be applied best for the phase change method and now no longer for increasing the temperature. Thus all through the discharge of latent heat, the temperature stays constant.
