Question

Carbon dioxide constitutes about _________ % by volume in air.

Answer 1

• Carbon dioxide constitutes about 0.04% of the volume of air and is the fourth most abundant component of air.
• Carbon dioxide gas is the most abundant gas on Mars and Venus.
• On earth, its percentage has increased by 40% since human industrialization as it is the main gas that is produced after the burning of substances.
• Carbon dioxide gas is the part of greenhouse gas that can trap sunlight and maintain the earth's temperature so that earth can be favourable for living organisms but after industrialization, the amount of carbon dioxide has increased in an environment due to which now global warming is now the matter of concern because the temperature of the earth is increasing and it has a very high disadvantage as the glaciers are melting and water level increases in the sea because of that land part is submerging in oceans.

Hence, carbon dioxide constitutes about 0.04 % by the volume in the air.
