Question

Define latent heat of fusion of ice give it's value

Answer 1

Ans: The amount of heat energy released or absorbed when a solid changing to liquid at atmospheric pressure at its melting point is known as the latent heat of fusion. ... The latent heat of fusion of water is 79.72 cal/gram (or) 334.0 kJ/Kg.

Answer 2

latent heat of fusion helps ice to change its sate of solid to liquid state .
When the temperature is increased the force of attractions between the particles of ice decreases results in increase of kinetic energy . After breaking down of almost all force of attractions when the ice reaches the melting point it changes to water.
