Imagine an ideal (carnot) refrigerator that keeps soda bottles chilled to a temperature of about 280 k. The refrigerator is located in a hot room with a temperature of about 300 k. Because of the imperfect insulation, 5. 00 j of heat is absorbed by the refrigerator each hour. How much electrical energy e must be used by the refrigerator to maintain the temperature of 280 k inside for one hour?.
