A Carnot freezer in a kitchen has constant temperature of 260k, while the air in the kitchen has a constant temperature of 300K. Suppose the insulation for the freezer is not perfect and energy is conducted into the freezer at a rate of .15 Watts. Determine the average power required for the freezer's motor to maintain the constant temperature in the freezer.
Qc/Qh=Tc/Th for a Carnot engine
efficiency = (Th - Tc)/(Th)
Work = Qh-Qc
