Air inside a closed container is saturated with vapour. The air pressure is 
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
B
C
No effect
D
Quadrupled
Text Solution
Verified by ExpertsThe correct answer is:
A
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.
