An ice-making machine inside a refrigerator operates in a Carnot cycle. It takes heat from liquid water at 0.0 C and rejects heat to a room at a temperature of 22.2 C. Suppose that liquid water with a mass of 86.2 kg at 0.0 C is converted to ice at the same temperature. Take the heat of fusion for water to be L_f = 3.34×10^5 J/kg.
How much heat |Q_H| is rejected to the room?
Q_H = -W = nRT_H(lnV2/V1)
(V2/V1)^gamma-1 = T1/T2 = Tc/Th
