Q. A certain brand of freezer is advertised to use 730 kWh of energy per year.

(a) Assume the freezer operates for 5 hours each day, how much power does it require while operating?
(b) If the freezer keeps its interior at a temperature of -5.0°C in a 20.0°C room, what is its theoretical maximum performance coefficient? 
(c) What is the theoretical greatest amount of ice this freezer could make in an hour, starting with water at 20 °C?
