Question

what are the uses of various gases in air

Answer 1

Answer:

Oxygen (O2): medical use, welding.

Nitrogen (N2): fire suppression, provides an inert atmosphere.

Helium (He): balloons, medical equipment.

Argon (Ar): welding, provides an inert atmosphere for materials.

Carbon dioxide (CO2): carbonated soft drinks.

Acetylene (C2H2): welding.

Answer 2

Answer:

A gas is a form of matter that does not have a defined shape or volume. Gases can consist of a single element, such as hydrogen gas (H2); they may also be a compound such as carbon dioxide (CO2) or even a mixture of several gases such as air.
