Question

Air inside a closed container is saturated with vapour. The air pressure is ρ and the saturated vapour pressure of water is P. If the mixture is compressed to one-half of its volume by maintaining temperature constant, the pressure becomes (A) 2 p+ barP (B) 2(ρ+ barP) (C) No effect (D) Quadrupled

Tardigrade Admin · Accepted Answer

Air inside a closed container is saturated with vapour, so if temperature remains constant, the saturated vapour pressure does not change. Also, pressure will be twice, when volume is halved.

Q. Air inside a closed container is saturated with vapour. The air pressure is $ρ$ and the saturated vapour pressure of water is $P$ . If the mixture is compressed to one-half of its volume by maintaining temperature constant, the pressure becomes

$2 p + \overset{ˉ}{P}$

$2 (ρ + \overset{ˉ}{P})$

No effect
