. d. A change of state from state 1 to state 2 produces a greater increase in entropy when carried out irreversibly than when done reversibly. e. The heat q for an irreversible change of state from state 1 to 2 might differ from the heat for the same change of state carried out reversibly. f. For a reversible isothermal process in a closed system, ΔS must be zero. g.The system's entropy change for an adiabatic process in a closed system must be zero. h.Thermodynamics cannot calculate ΔS for an irreversible process.
True or False. Explain your answers. a. For every cyclic process, the final state of the system is the same as the initial state. b. For every cyclic process, the final state of the surroundings is the same as the initial state of the surroundings. c. U and H depend only on T for a perfect gas. d. A change of state from state 1 to state 2 produces a greater increase in entropy when carried out irreversibly than when done reversibly. e.
