A 110 g copper calorimeter cup contains 205 cm3 of water and 50 g of ice, all in thermal equilibrium. A 215 g piece of iron is heated to a high temperature and dropped into the water (assume no water escapes the calorimeter cup). At thermal equilibrium the temperature of the entire mixture is 30 C. How much energy is required to melt all of the ice? How much energy is required to raise the temperature of the melted ice and water and copper cup to 30 C?
