Physics - Heat & Thermo Question with Solution | TestHub

A monoatomic 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 the expansion respectively, then the value of$\frac{T_1}{{ T}_2}$will be:
