B. Calculation of Heat during phase change. A phase change is a physical process in which a substance goes from one phase to another. The temperature of a substance does not change as the substance goes from one phase to another. The heat of fusion (AHfus) is the amount of heat per gram (or per mole) required for a phase change that occurs at the melting point. The heat of vaporization, (Hvap) is the amount of heat per gram (or...

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?
