Vapour Pressure And Effect Of Temperature

Explanation

Vapour Pressure

A liquid solution is made by dissolving a solid, liquid or gas in a liquid solvent. Vapour Pressure of liquid solution is characterised as the pressure applied by the vapours on the solvent in equilibrium condition and a specific temperature. It changes with the kind of liquid and temperature. A few properties of the vapour pressure of liquid solutions are as per the following:

• The pure liquid possesses more vapour pressure when contrasted with liquid’s solution.


• Vapour pressure is inversely proportional to attractive intermolecular forces within a liquid.


• Vapour pressure of a liquid increases with a rise in temperature, as molecules obtain kinetic energy and vaporise readily.
