Halliday, Resnick & Walker — Entropy and the Second Law of Thermodynamics: Problem 17

In Fig. 20.7, where $V_{23} = 3.00V_1$, $n$ 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 $1 \rightarrow 2$, what are (d) $W/nRT_1$, (e) $Q/nRT_1$, (f) $\Delta E_{\text{int}}/nRT_1$, and (g) $\Delta S/nR$? For path $2 \rightarrow 3$, what are (h) $W/nRT_1$, (i) $Q/nRT_1$, (j) $\Delta E_{\text{int}}/nRT_1$, (k) $\Delta S/nR$? For path $3 \rightarrow 1$, what are (l) $W/nRT_1$, (m) $Q/nRT_1$, (n) $\Delta E_{\text{int}}/nRT_1$, and (o) $\Delta S/nR$?
