(a) Define the term ‘latent heat of fusion’ of a solid. How much is the latent heat of fusion of ice?

(b) Draw a labeled diagram of the experimental set-up to study the latent heat of fusion of ice.

(a) The latent heat of fusion (or melting) of a solid is the quantity of heat in joules required to convert 1 kilogram of the solid (at its melting point) to liquid, without any change in temperature. The latent heat of fusion of ice is 3.34 × 105 joules per kilogram (or 3.34 × 105 j/kg).

(b) Experimental set up to demonstrate the latent heat of fusion-
