What is Heat Of Fusion?

The heat of fusion (enthalpy of fusion, ΔH_fus) is the amount of heat energy required to convert one mole of a solid substance into a liquid at constant pressure and at its melting point. It is an endothermic process because energy must be supplied to overcome the intermolecular forces holding the solid structure together. The heat of fusion for water is 6.01 kJ/mol, which is why melting ice absorbs significant amounts of heat from the surroundings.
