Latent heat of fusion is defined as the amount of heat energy required to change 1 kg of a solid into liquid at atmospheric pressure without any change in temperature at its melting point.

Hi friend,
The heat that we supply during melting of a liquid is called latent heat of fusion. It is called saw as the temperature doesn't rise if we provide continuous heat to the ice. ie. heat remains hidden from the thermometer.
Latent heat of fusion is amount of geat energy that is required to change one unit mass of solid to Liquid at atmospheric pressure at its melting point.
SI unit of latent heat of fusion is Joule per kilogram (J/kg).
The latent heat kr fusion of ice is 3.35×10^5 J/kg.
Thus,Ice at 0°C is more effective than cooling than the same quantity of water at same temperature (0°C).
Hope it Helps!!!!!!
