P-V plot for two gases (assuming ideal) ...

P-V plot for two gases (assuming ideal) during adiabatic processes are given in the Fig. Plot A and plot B should correspond respectively to:

A

`He` and `H_(2)`

B

`H_(2)` and `He`

C

`He` and `Ne`

D

`H_(2)` and `Cl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
2
`PV=` constant for isothermal process
`PV'=` constant for adiabatic process so more value of `gamma`, more decreases in pressure.
