A refrigerator with a coefficient of performance of 4 transfers heat from a cold region at -20C to a hot region at 30C. Calculate the total entropy change of the regions when 1 kJ of heat is transferred from the cold region.Is the second law satisfied? Will this refrigerator still satisfy the second law if its coefficient or performance is 6?
