Question

The correct sequence of the following Greenhouse Gases in order of increasing global warming potential (in a time horizon of 20 years) is:
A) Methane
B) Carbon dioxide
C) Nitrous Oxide
D) Sulfur hexafluoride
Select the correct answer using the code given below
1. A-B-C-D
2. B-A-C-D
3. D-C-B-A
4. C-A-B-D

Answer 1

Correct Answer - Option 2 : B-A-C-D

The Correct answer is B-A-C-D.

• Greenhouse Gases (GHGs): Atmospheric gases like carbon dioxide, methane, nitrous oxide (N2O), water vapour, etc are capable of trapping the out-going infrared radiation from the earth‘s surface thereby causing the greenhouse effect. Hence these gases are known as greenhouse gases and the heating effect is known as the greenhouse effect.
• Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere up to a specific time horizon, relative to carbon dioxide.

1. Carbon dioxide(CO2)-1
2. Methane(CH4)-56
3. Nitrous Oxide(N2O)-280
4. Sulphur hexafluoride(SF6)-16300
