The specific latent heat fusion is the heat energy needed to change 1 kg of the ice in its solid state at its melting point to 1 kg of the ice in its liquid state, and that released when 1 kg of the liquid changes to 1 kg of solid

Specific heat of fusion of ice is 0.336 MJ/kg

The specific latent heat of vaporisation of a water is the heat energy needed to change 1 kg of the water in its liquid state at its boiling point to 1 kg of the water in its gaseous state, and that released when 1 kg of vapour changes to 1 kg of liquid

Specific heat of vaporisation of water is 2.26 MJ/kg
