n = 1 moles of a monoatomic ideal gas are initially in a thermodynamic equilibrium state A characterized by temperature TA and volume VA. The gas is then brought to a second equilibrium state B, where VB = 2VA, by means of a reversible isothermal expansion. Then, it goes to a third equilibrium state C, where Vc= 3VB and Tc= TB/2, by an irreversible adiabatic expansion. After that, a reversible isothermal compression brings the gas to an equilibrium state D, where pp = pPA. Finally, the gas is heated and completes the cycle by a reversible isobaric process. a) Draw the (V, p) diagram of the cycle. Then, find: b) The heat exchanged by the gas during the cycle. c) The total work done by the gas during the cycle. d) The efficiency of the cycle. e) The variation of entropy of the universe ASu after a cycle.
