Kinetic Theory of Gases: Practice Problem & Solution
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: (1988)
Solution Explained:
To solve this problem, we apply the core principles of Kinetic Theory of Gases. Understanding the underlying formula is key to arriving at the correct answer below:
Vapour pressure of a liquid depends only on the nature of the liquid and its temperature. It is independent of the amount of liquid or the volume of the container. Since both are at the same temperature, the vapour pressure will be the same, so the ratio is 1:1.
