Question

What are the uses of the various gases in air?

Answer 1

Explanation:

Air is a natural virtue on earth which sustains life. It exists in the atmosphere and it basically contains a mixture of numerous gases like oxygen, nitrogen and carbon dioxide in higher proportions and much smaller levels of argon, water vapor, and other gases. Air also contains bacteria, suspended dust, and spores. However, the chemistry of air is really fascinating.

Air is a non-visible form of matter which is free-flowing and in the gaseous state. We cannot see it, taste it but sometimes smell it. However, air is a known matter and like all matter, it has weight, is compressible, and takes up space. Meanwhile, the components of air and its properties are mostly studied in chemistry as well as in physics.

Important Uses of Air

Air is a natural resource and is available abundantly. When we talk about the uses of air, the first thing that we can say that it is the most important element that supports the vitality and well being of all living things on the Earth. Having said that, just like water, air is very useful and it has a lot of applications.

Sustain life and growth

Combustion

Maintaining Temperature

Supplier of Energy

Photosynthesis

Answer 2

Answer:

Air is made up of $78.09\%$ nitrogen (N₂), $20.95\%$ oxygen (O₂), $0.93\%$ argon (Ar), $0.04\%$ carbon dioxide (CO₂), and other gases in mere amounts.

Oxygen:-

• Oxygen gas is essential for respiration in humans along with most of living organisms.  
• In addition to this, oxygen is used in industrial processes as well.

Nitrogen:-

• Sometimes nitrogen mixed with carbon dioxide, helps in food preservation.
• Instead of argon, some incandescent bulbs contain nitrogen gas.
• Nitrogen gas acts as good fire suppression agent and also used as inflate tires and  air bags in automobiles instead of air.
• Nitrogen is used for asphyxiation as a form of euthanasia.

Helium:-

• As helium is less dense than air, so it is used to fill balloons,.  So balloons float.
• Helium is used in pressurizing , leak detection, and purging gas systems.
• Helium atmosphere is used to grow crystals of silicon, germanium, titanium, and zirconium.

Carbon dioxide:-

• Plants need carbon dioxide to perform photosynthesis.
• Carbon dioxide makes bubbles in beer and sparkling wine.
• It is a common food additive used to regulate acidity.
• It is also used in lasers, fire extinguishers and dry cleaning.

Argon:-

• Argon is used to prevent the combustion of graphite itself in graphite furnaces.
• Argon is also used to fill the fluorescent lamp to prevent the oxidation of filaments at high temperatures.
• Argon is used as a blue laser often to destroy tumors and to cure eye defects and .
• To produce a bluish-green laser, argon is used.
