Physics - Heat & Thermo Question with Solution | TestHub

For two different gases $X$ and $Y$, having degrees of freedom $f_1$ and $f_2$ and molar heat capacities at constant volume ${\mathrm{C}}_{{\mathrm{v}}_1}$ and ${\mathrm{C}}_{{\mathrm{v}}_2}$ respectively, for adiabatic process, the $\ln \mathrm{P}$ versus $\ln \mathrm{V}$ graph is plotted as shown :-
