Composition of air
Answers
Answer:
Explanation:
The Composition of air is basically Oxygen — 21 percent. Argon — 0.93 percent. Carbon dioxide — 0.04 percent. Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor, by volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.

➩What is Composition of Air?
All the components that mix together to form air are composition of air.The atmosphere is a huge blanket of air that surrounds the earth. It provides us the air we breathe and protects us from the harmful effects of the sun’s rays.
➩Composition of Air
Earth's atmosphere is composed of air. Air is a mixture of gases having 78% nitrogen, 21% oxygen and small amounts of other gases too like carbon dioxide, argon,neon, hydrogen and various other components.
(i) Nitrogen
• Nitrogen is very important for plant’s survival. They cannot take nitrogen directly from the air. Bacteria that live in the soil and root nodules of some plants take nitrogen from the air and change its form so that plants can use it.
(ii) Oxygen
• Oxygen is the second most plentiful gas in the air. Humans and animals take oxygen from the air. Green plants produce oxygen during photosynthesis.Oxygen supports burning and is very important for plant survival. Thus, oxygen really plays a vital role in life.
(iii) Carbon dioxide
• Carbon dioxide is another important gas. Green plants use carbon dioxide to make their food and release oxygen. Humans or animals release carbon dioxide. The amount of carbon dioxide released by humans or animals seems to be equal to the amount used by the plants which make a perfect balance.
➩More To Know
The first scientific studies of atmospheric composition began in the 18th century, as chemists such as Joseph Priestley, Antoine Lavoisier and Henry Cavendish made the first measurements of the composition of the atmosphere.
