@S05727@ in which the dispersed phase is a solid, a liquid or a mixture of both and the continuous phase is a gas (usually air).
  1. Owing to their size, the particles of the dispersed phase have a comparatively small @S05631@ and hence exhibit some degree of stability in the earth's gravitational field.
  2. An aerosol can be characterized by its chemical composition, its @R05092@ (if any), the particle size distribution, the electrical charge and the optical properties.
  3. Modified from previous definition, within which particles with equivalent diameters usually between \(0.01\) and \(100\ \unicode[Times]{x3BC}\text{m}\) are specified. This extends beyond the size range specified for a @C01172@ system. To avoid confusion the definition proposed here is recommended.
