Question

Define latent heat of fusion​

Answer 1

Answer:

Explanation:

The amount of heat required to convert one unit amount of substance from the solid phase to the liquid phase — leaving the temperature of the system unaltered — is known as the latent heat of fusion.

For example, when a pot of water is kept boiling, the temperature remains at 100 °C (212 °F) until the last drop evaporates, because all the heat being added to the liquid is absorbed as latent heat of vaporization and carried away by the escaping vapour molecules.

Specific latent heat is the amount of energy required to change the state of 1 kilogram (kg) of a material without changing its temperature. ... latent heat of vaporisation - the amount of energy needed to boil or condense the material at its boiling point.
