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

Options

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.

Answer

A, B, D

Explanation

`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
