Question

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 of performance is 6?
