A heat pump is used to meet the heating requirements of a house and maintain it at 20°C. On a day when the outdoor air temperature drops to -2°C, the house is estimated to lose heat at a rate of 63,000 kJ/h. If the heat pump under these conditions has a COP of 1.8, determine the rate at which heat is absorbed from the cold outdoor air. Select one: a. 28,000 kJ/h b. 58,000 kJ/h c. 38,000 kJ/h d. 48,000 kJ/h NEED ASAP. I WILL UPVOTE
