A monatomic idea! gas of temperature T1 ...

A monatomic idea! gas of temperature `T_1` is being confined within a cylinder having frictionless piston. When the piston is released the gas is expanded adiabatically and its temperature becomes `T_2`. If the length of the gas column before and after the expansion becomes `L_1` and `L_2` respectively, then `T_1/T_2` becomes

A

`(L_1/L_2)^(2/3)`

B

`L_1/L_2`

C

`L_2/L_1`

D

`(L_2/L_1)^(2/3)`
