Question

What happens if the percentage of carbon dioxide increases in the air?

Answer 1

Hint: Carbon dioxide forms 0.03 percent by volume of the atmosphere. Carbon dioxide traps heat as they are transparent to sunlight., if the amount of carbon dioxide increases, the greenhouse gets disturbed and carbon dioxide is a major contributor to global warming. Increase in levels of carbon dioxide also affects human health.

Complete step by step solution:
-Carbon dioxide is released into the atmosphere by respiration, burning of fossil fuels, decomposition of calcium carbonate during the manufacturing of cement.
-during volcanic eruptions also carbon dioxide is released. Carbon dioxide gas is confined to troposphere only. Carbon dioxide forms 0.03 percent by volume of the atmosphere.
-when the use of fossil fuels is increased, a large amount of carbon dioxide is released into the atmosphere.
-excess of carbon dioxide is removed by green plants and this results in maintenance of appropriate levels of carbon dioxide in the atmosphere.
-green plants require carbon dioxide for photosynthesis and they release oxygen thus maintaining balance.
-when the level of carbon dioxide increase, it disturbs the balance in the atmosphere. The increased amount of carbon dioxide in the air is mainly responsible for global warming.
The increased percentage of carbon-dioxide will cause the greenhouse effect, i.e. it will not allow the hot rays of the sun to escape from the atmosphere after reflection once they enter the earth's atmosphere, thereby increasing the temperature of the earth, ice on mountains will melt and the water level will rise.

Note: Carbon dioxide traps heat as they are transparent to sunlight., if the amount of carbon dioxide increases, the greenhouse gets disturbed and carbon dioxide is a major contributor to global warming. Lime water turns milky when exposed to air and stirred as lime water mixes with $CO_2$​ and forms $CaCO_3$ ​(calcium carbonate) which turns the lime water milky. This shows air contains $CO_2$. Increase in the level of carbon dioxide results in an increase in global temperature which in turn increases infectious diseases like dengue, malaria etc.it also increases the frequency of floods, storms etc.
