Question

smoke and fog both are aresols . In what way are they diffrent?

Answer 1

the solvent in both smoke and fog is the same air but the solute is different
for fog it is water droplets and for smoke it smoke particles dust Ash soot etc.

Answer 2

They differ by their composition. They both are colloidal mixtures but smoke is consists of air mixed with carbon particles but fog consists of air mixed with water vapour ( mostly).

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 .
