Monoatomic , diatomic and triatomic gase...

Monoatomic , diatomic and triatomic gases whose initial volume and pressure are same, each is compressed till their pressure becomes twice the initial pressure. Then:

A

if the compression is isothermalthen their final volumes will be same

B

it if compression is adiabatic, then final volume will be different

C

if the compression is adiabatic, then triatomic gas will have maximum final volume

D

if the compression is adiabatic, then monoatomic gas will have maximum final volume.

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
`P_(1)V_(1)^(gamma)=P_(2)V_(2)^(gamma)impliesP_(0)V_(0)^(gamma)=2P_(0)V_(2)^(gamma)`
`V_(2)=((1)/(2))^(gamma)V_(0)`
`V_(2)=(V_(0))/(2^(gamma))`
triatomic gase `gamma` is mas `V_(2)` is minimum
