Answer 2

Explanation:

A saturated solution can be converted into unsaturated solution by increasing the amount of solvent .

Dissolved air in water contains a higher percentage of oxygen than ordinary air.

At low temperatures the solubility of a gas in water is less compared to that at ordinary temperatures.

Efflorescence occurs when the vapour pressure of the hydrated crystals is more than the vapour pressure of the atmospheric humidity.
