Halliday, Resnick & Walker — Entropy and the Second Law of Thermodynamics: Problem 25

25 Figure 20-25 shows a reversible cycle through which 1.00 mol of a monatomic ideal gas is taken. Volume \(V_c = 8.00V_b\). Process \(bc\) is an adiabatic expansion, with \(p_b = 5.00\text{ atm}\) and \(V_b = 1.00 \times 10^{-3}\text{ m}^3\). For the cycle, find (a) the energy added to the gas as heat, (b) the energy leaving the gas as heat, (c) the net work done by the gas, and (d) the efficiency of the cycle.
