Halliday, Resnick & Walker — Entropy and the Second Law of Thermodynamics: Problem 21

21 In Fig. 20-23, where \(V_{23} = 4.00V_1\), \(n\) moles of a diatomic ideal gas are taken through the cycle with the molecules rotating but not oscillating. What are (a) \(p_2/p_1\), (b) \(p_3/p_1\), and (c) \(T_3/T_1\)? For path 1 → 2, what are (d) \(W/nRT_1\), (e) \(Q/nRT_1\), (f) \(\Delta E_{int}/nRT_1\), and (g) \(\Delta S/nR\)? For path 2 → 3, what are (h) \(W/nRT_1\), (i) \(Q/nRT_1\), (j) \(\Delta E_{int}/nRT_1\), and (k) \(\Delta S/nR\)? For path 3 → 1, what are (l) \(W/nRT_1\), (m) \(Q/nRT_1\), (n) \(\Delta E_{int}/nRT_1\), and (o) \(\Delta S/nR\)?
