One hundred kilojoules of heat are transferred from a heat reservoir at 600 k to the environment at 300 k 61 find the change in entropy of each reservoir in kj k1 (4) 62 is the sum in agreement with the second law? (4) 63 determine the total entropy changes if the temperature of the environment was only 275 k (2) 64 determine the additional loss in work potential (work which could have been done by the system) if the temperature of the environment was lowered from 300 k to 275 k
