In a refrigerator one removes heat from a lower temperature and deposites to the surroundings at a higher temperature. In the process, mechanical work has to be done , which is provided by an electric motor. If the motor is of `1kW` power , and heat is 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.
