Answer 1

The various gases that make up air and their importance is as follows:

2. Oxygen: Most living beings require it to breathe and live. It supports combustion.
3. Argon: It makes a good atmosphere for working with air-sensitive materials since it is heavier than air.
4. Carbondioxide: Plants require it for photosynthesis to synthesize glucose.
5. Neon: Neon gives a distinct reddish-orange glow and is used as neon glow lights and also as a refrigerant.
6. Helium: It is used to life up balloons as it is lighter than air and non-combustible.
