How many different gases are in the air?
There are a lot of gases in the air around us, but most of the air is made up of just three gases—nitrogen, oxygen, and argon. There are smaller amounts of carbon dioxide and water vapor. And there are about ten more gases in amounts so tiny that people seldom talk about them. Of course, the list doesn't stop, either. Anything that you can smell—like roses or cheese or onions—must have some chemical that is carried as a gas in the air. So if you want to think of things like that, then the list of gases in the air would go on and on. I hope you do not want me to name them all because I doubt that anyone really knows. |
