Air is made up of a mixture of gases including oxygen, nitrogen, and carbon dioxide. It also contains water vapor—water in the form of a gas. The temperature of the air determines how much water vapor it can hold: warm air can hold more than cool air. When the air is saturated, it cannot hold any more, and any extra water vapor will condense into liquid form.
