The interior of a refrigerator has a surface area of 2. 8 m². It is insulated by a 1. 5 cm thick material that has a thermal conductivity of 0. 0219 J/m·s·◦C. The ratio of the heat extracted from the interior to the work done by the motor is 4. 4% of the theoretical maximum. The temperature of the room is 37. 7 ◦C, and the temperature inside the refrigerator is 3. 7 ◦C. determine the power required to run the compressor.
