Question

Which of the following Gases combination are commonly referred to as greenhouse gases?

1. CO₂, CH₄, N₂O, HFC and sulfur hexafluoride
2. chlorofluorocarbons, O₂, NH₃ and N₂
3. chlorofluorocarbons, H₂,  and N₂
4. Water vapor, O₂, CH₄, N₂O, and N₂ 

Answer 1

Correct Answer - Option 1 : CO₂, CH₄, N₂O, HFC and sulfur hexafluoride

• Gases combination CO₂, CH₄, N₂O, HFC and sulfur hexafluoride are commonly referred to as greenhouse gases.
• The Kyoto Protocol covers six greenhouse gases: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.
• Of these six gases, CO₂, CH₄, N₂O, are of primary concern because they are closely associated with human activities.
• A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect on planets.
