Air is soluble in water, and the solubility of air in water follows Henry’s Law – “the amount of air dissolved in a fluid is proportional to the pressure in the system”. Therefore, when we pump air through water, the air is at a higher pressure than water and so the un-dissolved air come out as air bubbles.
