Question
How is excessive content of CO2 responsible for global warming?
Solution
Due to the excess combustion, the concentration of CO2 increases beyond a certain level. Some of the CO2 is utilised by plants during photosynthesis and O2 is released into the atmosphere while the remaining concentration of CO2 will always remain unutilized. This excess CO2 absorbs heat radiated by the earth. Some of it is dissipated into the atmosphere while the remaining part is radiated back toward the earth’s surface and other bodies present on the earth. As a result, the temperature of the earth and other bodies on the earth increases. This is called greenhouse effect and CO2 is called green house gas. Due to green -house effect, global warming occurs which has serious consequences.
