The dispersed phase and dispersion medium in smoke, respectively, are:
The dispersed phase and dispersion medium in smoke, respectively, are:
Show Hint
- solid, gas
- gas, gas
- gas, solid
- solid, solid
The Correct Option is A
Solution and Explanation
Smoke is a colloidal system in which solid particles (such as carbon and other particulates) are dispersed in a gaseous medium (air).
- Dispersed Phase: Solid particles
- Dispersion Medium: Gas (air) Such systems are categorized as aerosols, which include both smokes (solid in gas) and fogs (liquid in gas).
