    mcq: change of entropy-Carnot cycle

    mcq: change of entropy-Carnot cycle In the Carnot Cycle, equations are there for the change of entropy in a process. Increase of entropy is undesirable as it reduces availability. Entropy of a refrigerant is zero in S.I. units at a temperature of 00C -400C +1000C (None Ans: (ii) Change of entropy during heating at constant […]
