Question

Smoke and fog both are aerosols. In what way are they different?

Answer 1

Colloids Are classified according to the physical state of dispersed phase (solute) & the dispersion medium (solvent).

Aerosol:
An aerosol is a colloid in which a solid or liquid is dispersed in a gas (including air).

Smoke and fog both are aerosols but their dispersed phase is different.

The dispersed phase in fog is liquid (water droplets) whereas the dispersed phase in smoke is solid (particulate matter). Both fog and smoke have gas at the dispersion medium .


OR

Though both smoke and fog are aerosols ,, there is a difference betwenn the two

Fog: Droplets of water vapour suspended in the air near the ground. An atmosphere in which visibility is reduced because of a cloud of some substance. Non-pollutant.

Smoke: A hot vapour containing fine particles of carbon being produced by combustion. A cloud of fine particles suspended in a gas. Highly pollutant.
