Question

Why air is not pure in car silencer or exhaust​

Answer 1

Answer:

Air is not pure in car silencer or exhaust because exhaust gas consists of nitrogen, water vapour, and carbon dioxide.

Explanation:

Exhaust gases are produced as a result of combustion of a mixture of hydrocarbons like gasoline or petrol with air. It is discharged into the atmosphere through an exhaust pipe. These emissions are one of the major contributors to air pollution. They also cause smog in some of the major cities due to the increased number of vehicles.

Answer 2

Answer:

Air is not pure in car silencer or exhaust because nitrogen, water vapour, and carbon dioxide account for the majority of the exhaust gas.

Explanation:

The burning of a mixture of hydrocarbons (gasoline/petrol) with air produces exhaust gas. As a result, nitrogen, water vapour, and carbon dioxide account for the majority of the exhaust gas. So the air is not pure in car silencer or exhaust.

Passenger vehicles are a major source of air pollution, emitting large volumes of nitrogen oxides, carbon monoxide, and other pollutants.
