Air is a mixture for of the following reasons:
1. Air does not have a fixed composition. Its composition varies from place to place.
2. The components of air can be separated by a physical method such as fractional distillation of liquid air.
3. Liquid air does not have a definite boiling point.
4. We can prepare air artificially by mixing the various components of air in the same proportions in which they occur at a place. This is a physical process because no energy changes occur.
