P-V plots for two gases during adiabatic...

P-V plots for two gases during adiabatic processes are shown in the figure. Plots 1 and 2 should corresponds respectively to

`He and O_2`

`O_2 and He`

`He and Ar`

`O_2 and N_2`

Text Solution

Verified by Experts

The correct Answer is:

In an adiabatic process, slope of P-V graph `=(dP)/(dv) =-gammaP/V`
i.e. slope `propgamma` (with - ve sign)
So `("slope")_2 gt ("slope")_1 :.gamma_2gt gamma_1`
`:.` plot 1 correspnds to `O_2 (gamma=1.4)` and Plot 2 corresponds to He `(gamma=1.67)`
