Hint: Smoke contains tiny particles of unburned carbon. Smoke is a colloidal solution of solid particles like carbon, dust which are dispersed in air. Fog is condensed droplets of water in the air. A mixture of smoke which gets stuck in the air with fog is a common phenomenon in the winter season.
Complete solution:
We know that smoke contains tiny particles of unburned carbon. Smoke is a colloidal solution of solid particles like carbon, dust which are dispersed in air.
Smoke is a main source of air pollution. The particles of smoke are injurious to health. Thus, the particles of smoke need to be precipitated.
Smoke is formed when particles of dust get mixed with air. . Formation of smoke is a source of air pollution.
Fog is formed when water vapours condense to form liquid water droplets that hang in air. Fog consists of very tiny droplets of water that are dispersed in air.
When smoke and fog combine together smog is produced.
Smog could be seen if there is no wind flowing in the area. The main sources of smog are automobile exhausts, power plants that burn coal, burning of fossil fuels, etc.
Thus, smoke + fog is called smog.
Thus, the correct option is (A)
Note:There are two types of smog: Photochemical smog and classical smog. Photochemical smog results as a photochemical reaction between ultraviolet radiation and the pollutants present in air. Classical smog is a mixture of smoke and fog. Classical smog is also known as London smog.
