The temperature inside a kitchen freezer is a constant 256 K, while the temperature of the air in the kitchen is a constant 302 K. The freezer's insulation is imperfect, and it conducts energy into its interior at a rate of 0.150 W. Assuming the freezer can be approximated as ideal (operating in a Carnot cycle), what is the average power required by the freezer's motor to maintain the constant interior temperature? W
