The vapour pressure of water at 20 degree celsius 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).
8.77 mmHg
17.54mmHg
35.08 mmHg
between 8.77 and 17.54mmHg

Vapour pressure is NOT impacted by volume! In a container, the liquid and vapor are in balance. Some of the vapor in the container changes from a vapor state to a liquid state when the volume is altered, for example, lowered. Additionally, part of the liquid will turn into its vapor state when the volume is raised.
