Aerosol

Also called an aerosol or aerosol. A type of dispersion system that uses gas as the dispersion medium. An example of a dispersion system in which the dispersed phase is a liquid is fog, and an example of a dispersion of a solid is smoke. It is not very stable, and if left in a container, the dispersed particles will often settle or adhere to the container walls. The so-called smog found in polluted air is a type of aerosol that contains suspended particulate matter.
