Two gases A and B, having the same temp. T, same pressure P and same volume V are mixed. If mixture occupies a volume V and has temp. T, the pressure of the mixture will be x P, where x = ?

Answer

2

Explanation

Here, `P_(1)=p, T_(1)=T`
`V_(1)=V +V_(2)=2V`
For the mixture , `P_(2)=? , V_(2)=V, T_(2)=T`
`P_(2)V_(2) = P_(1)V_(1)`
`P_(2)=(P_(1)V_(1))/(V_2) = (P(2V))/(V) = 2P = xP`
`:. X=2`.
