A metal piece weighing `15 g` is heated to `100^(@)C` and then immersed in a mixture of ice and water at the thermal equilibrium. The volume of the mixture is found to be reduced by `0.15 cm^(3)` with the temperature of mixture remaining constant. Find the specific heat of the metal. Given specific gravity of ice `= 0.92`, specific gravity of water at `0^(@)C = 1.0`, latent heat of fusion of ice `= 80 cal-g^(-1)`.
