A gas is enclosed in a vessel at a constant temperature and at a pressure of 2 atm and volume 4 liters. Due to a leak in the vessel after some time the pressure is reduced to 1.5 atm as a result if `5P%` of the gas escaped out then find the value of P.

Answer

5

Explanation

As `(V)/(T)=` constant
`(P_(1))/(n_(1))=(P_(2))/(n_(2))`
`n_(2)=(3)/(4)n_(1)`. So `75%` of gas still remaining and `25%` has escaped out .
