Question
A particularrefrigerator cools by evaporating liquefied chlorodifluoromethane,CCL2F2. How many kilograms of this liquidmust be evaporated to freeze a tray of water at 0' C toice at 0' C? The mass of the water is 525g, the heat of fusion ofice in 6.01 kJ/mol, and the heat of vaporization ofdichlorodifluromethane is 17.4 kJ/mol. Hint: apply negative sing to the heat offusion of ice, since heat energy is taken away from water. A particularrefrigerator cools by evaporating liquefied chlorodifluoromethane,CCL2F2.
