Uses of air:
Air, like water, is a valuable natural resource with numerous applications.
The most significant aspect of air is that it provides oxygen to all living beings on Earth.
Oxygen is used by more than just living organisms.
When exposed to oxygen, candles, fire, iron, and harvested fruits and vegetables all change.
To keep burning, candles and flames need air. When iron is exposed to water and oxygen, it rusts.
Because of the moisture and oxygen in the air, fruits and vegetables will change colour and eventually mould.
Air can also be utilised to generate electricity.
Windmills may convert the flow of air into electricity.
Boats, parachutes, flying objects, and the weather can all benefit from air (tornadoes, cyclones).
Final answer:
Hence, air is very essential for the livelihood.
