What is the correct order of the Global Warming Potential of the following atmospheric chemical species, from lowest to highest?
- Chlorofluorocarbon (CFC)
- Methane (CH4)
- Carbon dioxide (CO2)
- Nitrous oxide (N2O)
A1, 2, 4, 3
B3, 2, 4, 1 ✓ Correct
C3, 4, 2, 1
D1, 4, 3, 2
Correct answer: (B) 3, 2, 4, 1 — The order from lowest to highest is 3, 2, 4, 1.
Explanation
★The order from lowest to highest is 3, 2, 4, 1.
★Carbon dioxide has the lowest global warming potential, taken as the base, which is item 3.
★Methane has a higher potential than carbon dioxide, which is item 2.
★Nitrous oxide has a still higher potential than methane, which is item 4.
★Chlorofluorocarbons have the highest potential of the four, which is item 1.
★So the increasing order is carbon dioxide, methane, nitrous oxide and CFC.
★So the answer is 3, 2, 4, 1.
