Why is air classified as a mixture?

Answer 1

The best reason I can think of for why we believe that air is a mixture is that freezing air slowly yields different liquids at different temperatures. Liquid nitrogen has a different boiling point than liquid oxygen. They also freeze at different temperatures. If air were only 1 compound, then air in its entirety would have a single boiling point and a single freezing point.

Answer 2

Air is called a mixture because air contain not only one element or one compound; air contain many elements and compounds: nitrogen, oxygen, argon, carbon dioxide, water vapours, helium, neon, krypton xenon, ozone, radon, pollutants.

Answer 3

Air is called a mixture because its made up of gas and a small amount of water.You can tell this by when its foggy because there is more dew on the grass than on a regular morning.It also may possibly freeze the grass you step on.Thats my answer for why air is called a mixture

Answer 4

Air is a mixture because in air so many gases are present and they are seperately moving and not bonded by chemical bond.

Answer 5

because it contains several gasses: oxygen, nitrogen, carbon dioxide, and several others. The mix of these is "air"

Answer 6

Because it can be separated by physical methods.

Answer 7

Air is a combination of mostly Nitrogen, some Oxygen, a little Carbon Dioxide, and a very, very small amount of other gasses

Answer 8

hereogeneous mixtures

Answer 9

Because it is made up of different gases

Answer 10
