Problem 5 (25 points) A 22-53 block of ice at -43C is added to 273-g of water in a 76.2g copper calorimeter at an initial temperature of 26C. Determine the nal temperature of the system consisting of the ice, water, and calorimeter. You may assume all the ice melts. Remember that the ice must rst warm to 0C, melt, and then continue warming as water. (The specic heat of ice is 0.500 cal/g.C = 2090 J/kg.C. The latent heat of fusion of water is 79.7 cal/g. The specic heat of copper is 0.0924 cal/g.C.)
