What are the 4 main gases in the atmosphere?
The dry composition of the atmosphere is mostly nitrogen and oxygen. It also contains small amounts of argon and carbon dioxide and trace amounts of other gases, such as helium, neon, methane, krypton, and hydrogen.
What is atmosphere Class 3?
Thick envelop of air around the earth is called atmosphere. Air is a mixture of many gases like oxygen, nitrogen, carbon dioxide, argon etc. We inhale oxygen from air. Atmosphere contains 21% oxygen, 78% nitrogen and 1% other gases.
What are 3 types of gases?
Basically, gases are of three types.
- Elemental gasses. These are the elements that exist as gasses at standard temperature and pressure.
- Pure and mixed gases. Pure gases can be made up of individual atoms such as inert gases or can be comprised of a group of different atoms such as carbon dioxide.
- Toxic gases.
