Which of the following green house gases has the greatest heat trapping ability? |
| A. | Chlorofluoro carbon |
| B. | Methane |
| C. | Carbon dioxide |
| D. | Nitrous oxide |
| Answer» A. Chlorofluoro carbon | |
|
Explanation: Gases that trap heat in the atmosphere are called green house gases. Global Warming Potentials (GWPs) are used to compare the abilities of different green house gases to trap heat in the atmosphere. Carbon dioxide is used as the base for all the calculations, so its global warming potential is 1.2. The higher the GWP, the more heat the specific gas can keep in the atmosphere. |
