Question

Choose the correct statement regarding vapour pressure:

• A. It is calculated for an open vessel
• B. It does not depend upon surface area
• C. More the volume of container in which the liquid is present , more is the vapour pressure.
• D. (a) and (b) above.

Answer 1

The correct option is B It does not depend upon surface area

Vapour pressure:
The pressure exerted by vapours in thermodynamic equilibrium with its condensed phase at a given temperature in a closed system.
Vapour pressure does not depend on

1. Surface area
2. The shape of the container
3. The amount of liquid taken
