B and it contains half the amount of water in E. If both are at the same temperature, the water vapour in the containers will have pressure in the ratio of

Vapour is the gaseous state of a substance that is typically liquid or solid at room temperature. It forms when the substance evaporates or sublimates. Vapour can exist below its boiling point and can be seen as mist or steam when it condenses or reaches saturation in the air.

Class 11 Physics Chapter 10 Thermal Properties of Matter focuses on temperature and heat expansion of solids liquids and gases specific heat capacity latent heat and thermal conductivity. It explains thermal equilibrium laws of thermodynamics and methods of heat transfer such as conduction convection and radiation. It also covers the behavior of matter under varying thermal conditions.
