what is latent heat of fusion ?
Answers
Explanation:
Enthalpy of fusion a.k.a latent heat of fusion is the change in enthalpy of a substance when a specified amount of that substance is heated to change its state from solid state to liquid state. The temperature at which this happens is known as the melting point of that substance..

Here Is Your 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. For example, when melting 1 kg of ice (at 0 °C under a wide range of pressures), 333.55 kJ of energy is absorbed with no temperature change. The heat of solidification (when a substance changes from liquid to solid) is equal and opposite.
