What are the 5 components of air?
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..
Is Air made out of particles?
Around 78% of air is actually made up of another common gas called nitrogen. … This includes argon, carbon dioxide, helium, methane, and other trace gases. But that’s not all! You’ll also find other things in air, like dust, pollen, microbes, spores, and even water!
What percentage of air is made?
The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
Is air a gas or liquid?
Characteristics of Air In particular, oxygen and nitrogen, which are the major components of air, occur in nature as diatomic (2 atom) molecules. Under normal conditions, matter exists as either a solid, a liquid, or a gas. Air is a gas.
How do humans use air?

What does the air have?

Which gas is absent in air?
