Imagine an ideal (carnot) refrigerator that keeps helium in its liquid state, at a temperature of about 4.00 k. the refrigerator, with the helium container inside, is in a laboratory where the temperature is about 294 k. because of the imperfection of the insulation, 2.00 j of heat is absorbed by the refrigerator each hour. how much electrical energy e must be used by the refrigerator to maintain a temperature of 4.00 k inside for one hour?
