Question
Low visibility during cold weather is due to
Options
formation of fossil fuel
unburnt carbon particles or hydrocarbons suspended in the air
lack of adequate power supply
none of these
Solution
unburnt carbon particles or hydrocarbons suspended in the air
Explanation:
Low visibility during cold weather is due to the formation of smog. The combustion of fossil fuels increases the number of suspended particles in the air. These could be unburnt carbon particles or substances called hydrocarbons. The presence of high levels of all these pollutants causes the visibility to be lowered, especially in cold weather when water also condenses out of the air. This is known as smog and is a visible indication of air pollution.
