MICROANATOMY

Detailed explanation-1: -Explanation – Air is a mixture of gases. It contains water vapour, oxygen, carbon dioxide, nitrogen, dust, and smoke, among other things.

Detailed explanation-2: -It has many gases such as nitrogen, oxygen, carbon dioxide, carbon monoxide, water vapour and even dust particles. Dry air contains 20.95% oxygen, 78.09% nitrogen, 0.04% carbon dioxide, 0.93% argon and small amounts of other gases.

Detailed explanation-3: -The dry composition of the atmosphere is mostly nitrogen and oxygen. It also contains fractional amounts of argon and carbon dioxide and trace amounts of other gases, such as helium, neon, methane, krypton, and hydrogen (NASA).

Detailed explanation-4: -Nitrogen and oxygen are the major components of air. The other gases are carbon dioxide, water vapour, noble gases, etc. The composition of air is not fixed and varies slightly from place to place.

Detailed explanation-5: -Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.
