Unformatted text preview: ossible to create entropy? Is it possible to destroy it? 7–14C A piston-cylinder device contains helium gas. During a reversible, isothermal process, the entropy of the helium will (never, sometimes, always) increase. 7–15C A piston-cylinder device contains nitrogen gas. During a reversible, adiabatic process, the entropy of the nitrogen will (never, sometimes, always) increase. 7–16C A piston-cylinder device contains superheated steam. During an actual adiabatic process, the entropy of the steam will (never, sometimes, always) increase. 7–17C The entropy of steam will (increase, decrease, remain the same) as it flows through an actual adiabatic turbine. 7–18C The entropy of the working fluid of the ideal Carnot cycle (increases, decreases, remains the same) during the isothermal heat addition process. 7–19C The entropy of the working fluid of the ideal Carnot cycle (increases, decreases, remains the same) during the isothermal heat rejection process. 7–20C During a heat transfer process, the...
