Air is a homogeneous mixture.
Clean air is a homogeneous mixture of nitrogen, argon, oxygen, water vapor and several other gasses present in small amounts. Air that is not "clean" is air that contains dirt and dust, etc, and is a heterogeneous mixture.
Pure air is homogeneous because all components are completely miscible.
homogeneous
Air is a homogeneous mixture of several gases.
Air in your house is a homogeneous mixture because its components (oxygen, nitrogen, carbon dioxide, etc.) are uniformly distributed throughout the space.
Clean air is a homogeneous mixture of nitrogen, argon, oxygen, water vapor and several other gasses present in small amounts. Air that is not "clean" is air that contains dirt and dust, etc, and is a heterogeneous mixture.
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.
The filterred liquid is an homogeneous solution.
No
Unfiltered air is heterogeneous because it is composed of a mixture of different gases, particles, and possibly microorganisms. This means that the components are not uniformly distributed throughout the air.
