In a refrigerator one removes heat from a lower temperature and deposits to the surroundings at a higher temperature. In this process, mechanical work has to be done, which is provided by an electric motor. If the motor is of 1kW power and heat transferred from `-3^(@)` C to `27^(@)` C, find the heat taken out of the refrigerator per second assuming its efficiency is 50% of a perfect engine.
