The interior of a refrigerator has a surface area of 6 m². it is insulated by a 1.9 cm thick material that has a thermal conductivity of 0.0336 j/m·s◦c. the ratio of the heat extracted from the interior to the work done by the motor is 8.6 % of the theoretical maximum. the temperature of the room is 25◦c, and the temperature inside the refrigerator is 9 ◦c. determine the power required to run the compressor.
