The term homogenous has different possible meanings depending on the circumstance. Roughly speaking, a small volume of air is homogeneous. However, there are potentially different concentrations of gases in the air. Additionally, there are suspended dust particles which are non-uniformly distributed in the air. Thus, depending on the criteria used, air may be considered heterogeneous in some cases.
