(17%) Problem 4: A freezer has a coefficient of performance of 5.4. You place 0.35 kg of water at 21°C in the freezer, which maintains its temperature of -14°C. In this problem you can take the specific heat of water to be 4190 J/kg/K, the specific heat of ice to be 2100 J/kg/K, and the latent heat of fusion for water to be 3.34 x10 J/kg. A How much additional energy, in joules, does the freezer use to cool the water to ice at -14°C?
