Question

write two usesof air​

Answer 1

Uses of AIR are as follows:

1. Air contains oxygen, which is essential for life. All living things respire by breathing in air. The air we breathe in is inhaled air. The air we breathe out is exhaled air.

2. Air supports burning or combustion. The oxygen present in air is essential for burning. We burn fuels to cook food, generate heat and electricity, run industries and drive vehicles. The presence of nitrogen reduces the activity of oxygen. If air contained mostly oxygen, even small fires would turn into huge explosions!

3. The nitrogen present in air is essential for the growth of plants. Plants take in nitrogen directly from the air or from the soil.
