Expert Answer:

The enthalpy of fusion or heat of fusion is the change in enthalpy resulting from heating a given quantity of a substance to change its state from a solid to a liquid. The temperature at which this occurs is the melting point.


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. 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.
