A calorimeter contains 1.5 kg of water at a temperature of 20 ?C. One places 1 kg of ice at a temperature of -10 ?C in the calorimeter. Once thermal equilibrium is reached, what is the temperature in the calorimeter? The heat capacity of the calorimeter is negligible. The heat capacity of water and ice are, respectively, 4200 J/kg·K and 2100 J/kg·K. The heat of fusion of ice is 334 kJ/kg. Solve the above problem for the case when the ice has a mass of 0.1 kg.
