The heat of vaporization of water is 540 cal/g, and the heat of fusion is 80 cal/g. The heat capacity of liquid water is 1 cal g−1 °C−1, and the heat capacity of ice is 0.5 cal g−1 °C−1. 18 g of ice at -6°C is heated until it becomes liquid water at 40°C. How much heat was required for this to occur?
