WebThe values of latent heat for water are: Specific latent heat of fusion = 330 kJ kg -1. Specific latent heat of vaporisation = 2.26 MJ kg -1. Therefore, evaporating 1 kg of water requires roughly seven times more energy than melting the same amount of ice to form water. WebSpecific latent heat of fusion (The heat needed to change the substance from a solid at its melting point into liquid at the same temperature) and specific latent heat of vaporisation …
