Question:

When ice at 0oC melts to liquid water at 0oC, it absorbs 0.334 kJ of heat per gram. Suppose the heat needed to melt 31.5 g of ice is absorbed from the water contained in a glass. If this water has a mass of 0.210 kg and a temperature of 21.0oC, what is the final temperature of the water? (You will also have 31.5 g of water at 0oC from the ice.)
