Solution
The heat energy is supplied as latent heat of fusion. There is no change in the temperature till the entire solid has melted.
Latent heat of fusion is defined as the amount of heat gained by a solid object to convert into liquid form without the change in the temperature.
If the heat consumed by the substance is (Q), and m is the mass of the solid substance then the latent heat of fusion (L) is given by the formula: L= Q/m.
