A solid of mass 0.5kg initially at 50°C melts at 60°C. Calculate the quantity of heat required to melt it completely.
[Specific heat capacity of the solid = 1.0 kJkg-1k-1]
[Specific latent of heat of fusion of solid = 2.0kJkg-1]
[Specific heat capacity of the solid = 1.0 kJkg-1k-1]
[Specific latent of heat of fusion of solid = 2.0kJkg-1]
