Question

Chapter 20, Problem 42E

(a)

To determine

The number of joules of heat will the heat pump deliver to the inside for each joule of electrical energy used to run the unit, assuming an ideal Carnot cycle.

(b)

To determine

The amount of electrical energy required to deliver the same amount of heat to the inside as in part (a) when electrical resistance is used instead of heat pump and the heat pump delivers less heat for each joule of electrical energy used to operate the unit as the outside temperature decreases and this behavior is opposite to the dependence of the efficiency of a Carnot heat engine on the difference in the reservoir temperatures.
