$P-V$ diagram for two gases during adiabatic process are shown in the figure by curves $A$ and $B$ are for

A

$O_2\, and\, He$

B

$Ar\, and\, He$

C

$He\, and\, Ar$

D

$He\, and\, O_2$

Solution

$\mathrm{m}=$ slope $=-\gamma\left(\frac{\mathrm{P}}{\mathrm{V}}\right)$

$\mathrm{m}_{\mathrm{B}}>\mathrm{m}_{\mathrm{A}}$

$\therefore \gamma_{\mathrm{B}}>\gamma_{\mathrm{A}}$

A long cylindrical pipe of radius $20 \,cm$ is closed at its upper end and has an airtight piston of negligible mass as shown. When a $50 \,kg$ mass is attached to the other end of piston, it moves down by a distance $\Delta l$ before coming to equilibrium. Assuming air to be an ideal gas, $\Delta l / l$ (see figure) is close to $\left(g=10 \,m / s ^2\right.$, atmospheric pressure is $10^5 \,Pa$ ),
