Two gases A and B having the same temperature T, same pressure P and same volume V are mixed. If the mixture is at the same temperature and occupies a volume V. The pressure of the mixture is

Options

A. `2 P`
B. `p`
C. `p//2`
D. `4 p`

Answer

A

Explanation

Here , initially `p_(1)=p,V_(1)=V+V=2V`
`"finally "p_(1)=pV_(2)=V`
`"As " p_(1)V_(1)=p_(2)V_(2)`
`"or "P_(2)=(p_(1)V_(1))/(V)=(pxx2V)/(V)=2p`
