A vessel A has volume V and a vessel B has volume 2V. Both contain some water which has a constant volume. The pressure in the space above water is p a for vessel A and p b for vessel B.

1. Maximum pressure attainable by any liquid is saturation vapor pressure. Saturation vapor pressure is the pressure exerted by vapor above the surface of liquid when the air has become saturated.

2. When the air become saturated, pressure of the gas depends completely on temperature and not on volume of liquid.

3. So, in our case the water is same in both the vessel i.e. volume of water is same, and temperature of water is also constant.

4. Hence, pressure in both the vessel will be same.

A vessel A has volume V and a vessel B has volume 2V. Both contain some water which has a constant volume. The pressure in the space above water is pa for vessel A and pb for vessel B.
