Answer 1

Fog is water vapor in atmosphere which condenses due to low temperature and forms dense white thing in atmosphere,it is not a pollutant but it  reduces visibility.

Smoke is a collection of airborne solid and liquid particulates and gases emitted when a material undergoes combustion.

 Dispersed phase of smoke = Solid
Dispersion medium of smoke = Gas

Fog:

Dispersed phase : Liquid
Dispersing medium: Gas

Fog is formed by the condensation of water vapour in the lower layers of the atmosphere and smoke is the blackish gaseous particles released from combustion of fossil fuels. Fog reduces visibility and smoke causes breathing problems.
