A metal piece weighing 15 g is heated to 1000C 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 cm3 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 00C = 1.0, latent heat of fusion of ice = 80 cal-g-1
