- When we add a non-volatile solid to water, the boiling point of water will increase.
- In the case of a non-volatile solute, the vapour pressure is zero, so vapour pressure of solution will be less than the vapour pressure of solvent, the surrounding pressure for water to boil will need higher temperature and boiling point will increase.
- The boiling point of a liquid is the temperature at which the vapour pressure of the solution or liquid becomes equal to the Atmospheric Pressure.
- Adding salt does the very opposite of making the water boil faster. The salt actually increases the boiling point of the water, which is when the tendency for the water to evaporate is greater than the tendency for it to remain a liquid on a molecular level.
- The boiling point of a liquid varies depending upon the surrounding environmental pressure.
