The specific latent heat of fusion of ice is 334 kJ/kg (or 334 000 J/kg), and the specific latent heat of vaporization of water is 2260 kJ/kg (or 2 260 000 J/kg).
During the melting process, the temperature of the ice remains constant at 0°C. The heat energy supplied is used to break the hydrogen bonds holding the water molecules in a solid state (ice) and to increase the kinetic energy of the molecules as they transition to a liquid state (water). This energy input is the specific latent heat of fusion.
