In Fig. 20-25, where $V_{23}=$ $3.00 V_{1}, n$ 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) $W / n R T_{1}$,
(e) $Q \ln R T_{1}$,
(f) $\Delta E_{\text {int }} / n R T_{1}$, and
(g) $\Delta \operatorname{Sln} R ?$ For
path $2 \rightarrow 3$, what are (h) $W / n R T_{1}$,
(i) $Q / n R T_{1}$,
(j) $\Delta E_{\text {int }} / n R T_{1}, \quad(\mathrm{k})$
$\Delta S / n R ?$ For path $3 \rightarrow 1$, what are
(l) $W / n R T_{1}$,
$(\mathrm{m}) \quad Q / n R T_{1}$,
(n) $\Delta E_{\mathrm{int}} / n R T_{1}$, and (o) $\Delta S / n R ?$
