Container below are filled with three different gases as shown. Piston is made to oscillate in below three cases. Time Period of oscillation is TA, TB, TC. Then-

A

TA>TB> TC

B

TC> TA> TB

C

TC> TB> TA

D

TB> TA> TC

Answer

TC> TA> TB

Explanation

Solution

Time period of oscillation of piston is T µ 1r\frac{1}{\sqrt{r}} where

g = Cp/Cv adiabatic exponent

gmono = 5/3 ; gdi = 7/5; gpoly = 4/3

\ gmono > gdi > gpoly
