Boiling point class 9
WebThe boiling point of substance can be defined as, it is the temperature at which the vapour pressure of the substance equal to atmospheric pressure. According to Raoult s law, the vapour pressure of a solvent decreases in the presence of a non-volatile solute. Thus, the vapour pressure of a solution containing a non-volatile solute requires a high … WebMay 6, 2024 · The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. Therefore, the boiling point of a liquid depends on atmospheric pressure. The boiling point becomes lower as the external pressure is reduced. As an example, at sea level the boiling point of water is 100 C …
