1.	What is latent heat of fusion(solid to liquid)? Discuss in details.
Answer» It is quantity of heat in Joules which is required to convert unit mass or 1 kg solid into liquid form without rise in temperature. It has been found by experiments that 3.34 x10⁵ J of heat is required to convert 1 kg of ice in water at same temperature (0°C). So, latent heat of fusion of ice is 3.34 x10⁵ J/ Kg. Different substances have different Latent Heat of Fusion.

It is quantity of heat in Joules which is required to convert unit mass or 1 kg solid into liquid form without rise in temperature.

It has been found by experiments that 3.34 x10⁵ J of heat is required to convert 1 kg of ice in water at same temperature (0°C).

So, latent heat of fusion of ice is 3.34 x10⁵ J/ Kg.

Different substances have different Latent Heat of Fusion.
