Two containers A and B are partly filled with water and closed. The volume of A is twice that of B and it contains half the amount of water in B. If both are at the same temperature, the water vapour in the containers will have pressure in the ratio of
-
- 1 : 2
- 1 : 1
- 2 : 1
- 4 : 1
Correct Option: B
Vapour pressure does not depend on the amount of substance. It depends on the temperature alone.
