Aheat pump is a heat enginer run in reverse. in winter it pumps heat from the cold air outside into the warmer air inside the building, maintaining the building at a comfortable temperature. in summer it pumps heat from the cooler air inside the building to the warmer air outside, acting as an air conditioner.(a) if the outside temperature in winter is -5.0 degrees c and the inside temperature is 17.0 degrees c, how many joules of heat will the deat pump deliver to the inside for each joule of electrical energy used to run the unit, assuming an idel carnot cycle? (b) suppose you have the option of using electrical resistance heating rather than a heat pump. how much electrical energy would you need in order to deliver the same amount of heat to the inside of the house as in part (a)? consider a carnot heat pump delivering heat to the inside of a house to maintain it at 68 degrees f. showe that the heat pump delivers less heat for each joule of electrical energy used to operate the unt as the outside temperature decreases. notice that this behavior is opposite to the dependence of the efficiency of a carnot heat engine on the difference in the reservoir temperatures. explain why this is so. c) consider a carnot heat pump delivering heat to the inside of a house to maintain it at 68 ? f. show that the heat pump delivers less heat for each joule of electrical energy used to operate the unit as the outside temperature decreases. notice that this behavior is opposite to the dependence of the efficiency of a carnot heat engine on the difference in the reservoir temperatures. explain why this is so. do explain in detail for credit . many in advance.
