A "Carnot" refrigerator (reverse of a Carnot engine) absorbs heat from the freezer compartment at a temperature of -17°C and exhausts it into the room at 24°C.

(a) How much work must be done by the refrigerator to change 0.20 kg of water at 24°C into ice at -17°C

(b) If the compressor output is 200 W, what minimum time is needed to take 0.20 kg of 24°C water and freeze it at 0°C?
