(10) [12 points] A reversible engine contains 0.20 moles of monatomic ideal gas. Initially, the gas is at 600 K and confined to 2.0 L. The gas undergoes the following cycle: (A)$(B) Isothermal expansion to 4.0 L. (B)$(C) Constant volume cooling to 300 K. (C)9(D) Isothermal compression to 2.0 L. (D)$(A) Constant volume heating to 600 K. (a) Draw a PV diagram representing this cycle. (b) Which processes add heat? (c) For the processes where heat is added, calculate the heat in joules. (d) Calculate the net work in joules. (e) Calculate the efficiency of this engine. (f) Compare it to the efficiency of a Carnot engine operating between the same temperatures
