Chemistry - Ideal Gas Question with Solution | TestHub

Volume of container III > II > I

∴$T_{III}>T_{II}>T_I$ (∵ $P$ , $n$ same).

$U_{rms}=\sqrt{\frac{8RT}{\pi M}}$.

∴$(U_{rms}{)}_{III}>(U_{rms}{)}_{II}>(U_{rms}{)}_I$.

$\lambda =\frac{1}{\sqrt{2}\pi {\sigma }^{2}N}$, ∴ ${\lambda }_{III}>{\lambda }_{II}>{\lambda }_I$.

$Z_1=\sqrt{2}\pi {\sigma }^2\sqrt{\frac{8RT}{\pi M}},\frac{N}{V}$

$Z_1\propto \frac{1}{\sqrt{T}}$ ∴$(Z_1{)}_{III}<(Z_1{)}_{II}<(Z_1{)}_I$
