WebWhat is Condensation? Condensation is the process by which water vapour in the air is changed into liquid water. In other words, the water in the air, a gas known as water vapour. Condensation is the transformation of water vapour into liquid water, and the finest illustration is those enormous, fluffy clouds floating over your head. WebWe can therefore consider that humid air is formed of (1) dry air unlikely to condense under the temperature and pressure conditions considered here, and (2) water vapor likely to condense into liquid or ice.
