Question

Select One Correct Option from the following : A monatomic ideal gas, initially at temperature $T_{1}$, is enclosed in a cylinder fitted with a frictionless piston. The gas is allowed to expand adiabatically to a temperature $T_{2}$ by releasing the piston suddenly. If $L_{1}$ and $L_{2}$ are the lengths of the gas column before and after expansion respectively, then $T_{1} /T_{2}$ is given by
(A)$(L_{1} /L_{2} )^{2/3}$
(B)$L_{1} /L_{2}$
(C)$L_{2} /L_{1}$
(D)$(L_{2} /L_{1} )^{2/3}$
