Boiling Point of a Liquid
Boiling is a process of converting a liquid into its gaseous state at a definite temperature known as the boiling point of the liquid. Boiling is a first-order phase transition where the matter in the liquid state gets converted into the gaseous state. The boiling point or the boiling temperature of a liquid depends on the pressure above the liquid surface.
- A liquid boils when the vapor pressure of the liquid becomes equal to the atmospheric pressure. If atmospheric pressure is higher than its normal value boiling temperature of the liquid also increases.
- Addition of soluble salts changes the boiling point of liquids.
