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?

Research the melting point, boiling point, heat of fusion, heat of vaporization, and heat capacity values for ethanol. Use these values to sketch a heating curve for ethanol. The relative slopes of the rising portions and the lengths of the flat portions should correspond roughly with the values you researched. There is no need to mark any values on the x axis.
