The expressions that apply to the treatment of refrigerators also describe the behaviour of heat pumps, where warmth is obtained from the back of a refrigerator while its front is being used to cool the outside world. heat pumps are popular home heating devices because they are very efficient. compare heating of a room at 295 k by each of two methods: (a) direct conversion of 1.00 kg of electrical energy in an electrical heater, and (b) use of 1.00 kg of electrical energy to run a reversible heat pump with the outside at 260 k. discuss the origin of the difference in the energy delivered to the interior of the house by the two methods.
