The three properties of air that show it is a mixture are: (1) uniform composition, (2) components can be separated by physical means, and (3) each component retains its own properties in the mixture.
Air is a heterogenous mixture because it is composed of different gases like oxygen, nitrogen, carbon dioxide, and others that do not combine chemically. Each of these gases retains its own properties within the air mixture.
This is a mixture of liquids (ex.: liquid air).
Air, which is a mixture of gases, exerts pressure. We can see this as we observe a breeze moving the leaves of trees around. Air can be compressed, and we can demonstrate that if we blow up a balloon. Air is transparent, and we can't see it. There are other properties of air that are a little hard to see as air is a very light, transparent gas mixture.
Air is a mixture; the properties of the constituents of air (oxygen, nitrogen, carbon dioxide etc.) are not changed, and the mass ratios among them are not as consistent as they would be if air were a compound. On distillation of liquefied air, nitrogen predominantly distills off first, leaving behind oxygen in the liquid form. This is characteristic of a mixture, not of a compound.
Air is an example of a homogeneous mixture because its components (nitrogen, oxygen, argon, etc.) are uniformly distributed throughout, giving it a uniform composition and properties throughout.

As air is progressively cooled by your powerful refrigeration apparatus, it doesn't all liquefy at the same time. The carbon dioxide liquefies first, then the oxygen, then the nitrogen. You can separate these gases and demonstrate that they have very different properties.

Air is a mixture and not a compound because of the following reasons: Air can be separated into its constituents such as oxygen, nitrogen etc. by fractional distillation of liquid air. Air shows the properties of all the gases present in it.
Air is a mixture because it is composed of various gases like nitrogen, oxygen, carbon dioxide, and others that retain their individual properties and can be separated by physical means like fractional distillation. In contrast, compounds are chemically bonded substances that have a fixed composition and properties different from their constituent elements, which is not the case for air.
Homogeneous Mixture is defined as a mixture which has uniform composition and properties throughout. As an example, air is a homogeneous mixture of gases. A teaspoonful of table salt stirred into a glass of water also makes a homogeneous mixture.
The three properties of air are weight, mass, and density.

No, pure air is not homogeneous because it contains a mixture of different gases such as nitrogen, oxygen, carbon dioxide, and others. Each gas has a specific composition and properties, making the air a heterogeneous mixture on a molecular level.
