7. For an ideal Rankine cycle, the processes of turbine and pump are isentropic. 8. When a system is in thermal and mechanical equilibrium with the environment, the value of exergy is 9. The coefficient of performance of an irreversible refrigeration cycle is always less than the coefficient of performance of a reversible refrigeration cycle when each operates between the same two thermal reservoirs.

7. For an ideal Rankine cycle, the processes of turbine and pump are isentropic. 8. When a system is in thermal and mechanical equilibrium with the environment, the value of exergy is 9. The coefficient of performance of an irreversible refrigeration cycle is always less than the coefficient of performance of a reversible refrigeration cycle when each operates between the same two thermal reservoirs. 10. All reversible power cycles operating between the same two thermal reservoirs have the same thermal efficiency, regardless of the nature of the substance making up the system executing the cycle or the series of processes
