A. The entropy of steam will (increase, decrease, remain the same) as it flows through an actual adiabatic turbine.
B. During a heat transfer process, the entropy of a system (always, sometimes, never) increases.
C. Steam is accelerated as it flows through an actual adiabatic nozzle. The entropy of the steam at the nozzle exit will be (greater than, equal to, less than) the entropy at the nozzle inlet.
D. Heat is transferred at a rate of 2 kW from a hot reservoir at 800 K to a cold reservoir at 300 K. Calculate the rate at which the entropy of the two reservoirs changes and determine if the second law is satisfied.
