1. The formation of condensation on a glass of ice water causes the ice to melt faster than it would otherwise. If 7.10 g of condensation forms on a glass containing water and 230 g of ice, how many grams will melt as a result? Assume no other heat transfer occurs. Use the heat of vaporization of water at 37°, as an approximation, in this problem.

2. On a trip, you notice that a 2.24 kg bag of ice lasts an average of one day in your cooler. What is the average power in watts entering the ice if it starts at 0°C and completely melts to 0°C water in exactly one day? (1 watt = 1 joule/second or 1 W = 1 J/s.)
