A freezer has a coefficient of performance of 4.1. You place 0.45 kg of water at 16°C in the freezer, which maintains its temperature of -18°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 ×105 J/kg. How much additional energy, in joules, does the freezer use to cool the water to ice at -18°C?
