Question: A certain brand of freezer is advertised to use 880 kW*h of energy per year.

A) Assuming the freezer operates for 6 hours each day, how much power does it require while operating?

B) If the freezer keeps its interior at a temperature of -6.0°C in a 20.0 °C room, what is its theoretical maximum performance coefficient?

C) What is the theoretical maximum amount of ice this freezer could make in an hour, starting with water at 20.0 °C?
