Question

DEIFNE LATENT HEAT OF FUSION ?
​

Answer 1

Answer:

The enthalpy of fusion of a substance, also known as (latent) heat of fusion is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.

Answer 2

Answer:

Latent heat of fusion is the heat required to change 1 kg of a solid substance into liquid state at the melting point of the substance. For example, amount of heat required to melt ice at 0° C into water at 0° C, will be known as the Latent Heat of Fusion of ice.
