Answer: Solid and liquid
Explanation:
An aerosol is a suspension of fine solid particles or liquid droplets, in air or another gas.[1] Aerosols can be natural or anthropogenic. Examples of natural aerosols are fog, dust, forest exudates and geyser steam. Examples of anthropogenic aerosols are haze, particulate air pollutants and smoke.[dubious – discuss][1] The liquid or solid particles have diameters typically <1 μm; larger particles with a significant settling speed make the mixture a suspension, but the distinction is not clear-cut. In general conversation, aerosol usually refers to an aerosol spray that delivers a consumer product from a can or similar container. Other technological applications of aerosols include dispersal of pesticides, medical treatment of respiratory illnesses, and convincing technology.[2] Diseases can also spread by means of small droplets in the breath, also called aerosols (or sometimes bioaerosols).[3]
Aerosol science covers generation and removal of aerosols, technological application of aerosols, effects of aerosols on the environment and people, and other topics.
Aerosols, the atmospheric particles, consist of: D. Solid and liquid
Suspension is a heterogeneous mixture where the solute particles get suspended throughout the bulk of the solvent, then left floating around freely in the medium.
An aerosol is a suspension of fine solid particles or liquid droplets and it is in air or another gas. An aerosol is a gas containing very small particles of a solid or liquid with particle diameters in the range of [tex]10^-9[/tex] to [tex]10^-4[/tex]m.
Aerosols are come from volcanoes, dust storms, fires, vegetation, sea spray, burning of fossil fuels and land use. Primary aerosols are those particles emitted directly into the atmosphere. It is because the different sources of aerosols mix on the earth's surface. Warming aerosols are include black carbon and dark soot. Cooling aerosols include dust, sulfate particles and sea spray.
Aerosols can influence the Earth's climate in two ways. When the sky is clear (devoid of clouds), aerosols can reflect incoming sunlight back to outer space
Therefore aerosols, the atmospheric particles, consist of: Solid and liquid.
