A freezer has a coefficient of performance of 6.30. The freezer is advertised as using 525 kW-h/y. Note: One kilowatt-hour (kW-h) is an amount of energy equal to operating a 1-kW appliance for one hour. (a) On average, how much energy does the freezer use in a single day? (b) On average, how much thermal energy is removed from the freezer each day? (c) What maximum amount of water at 21.0°C could the freezer freeze in single day? (The latent heat of fusion of water is 3.33 x 10 J/kg, and the specific heat of water is 4186 J/kg - K.)
