Question
The vapour pressure of water at 20oC is 17.54 mmHg. What will be the vapour pressure of the water in the apparatus shown after the piston is lowered, decreasing the volume of the gas above the liquid to one half of its initial volume (assume temperature constant).
Options
A.8.77 mmHg
B.17.54 mmHg
C.35.08 mmHg
D.between 8.77 and 17.54 mmHg
Solution
Vapour pr. depends on temperature not volume.
