Both smoke and fog are aerosols that has gas as its dispersion medium. Smoke : Smoke is mixture of gases. It is formed by the incomplete combustion of fossil fuels such as coal, oil, and natural gas and carried on the hot air from burning. Dispersed phase in smoke is solid. Fog : Fog is the natural phenomenon when the humidity reaches 100%, in other words, the air is saturated with moisture and contains many tiny liquid water droplets collecting into the air at the surface of the Earth. The fog may rise to form a low layer of stratus. It is non- polluting. Dispersed phase in fog is liquid.
