Which of the following gases has the highest global warming potential (GWP) over a 100-year period?
medium Q4 of 15
Step-by-Step Solution
Step 1: Understand Global Warming Potential (GWP)
GWP measures how much heat a greenhouse gas traps compared to CO₂ over 100 years.Step 2: Compare GWP values
Sulfur hexafluoride (SF₆) has an extremely high GWP (~23,500), much higher than methane (~28), nitrous oxide (~265), and carbon dioxide (1).Final Answer:
Sulfur hexafluoride (SF₆) → Option AQuick Check:
Highest GWP gas = Sulfur hexafluoride ✅
Quick Trick: Remember SF₆ has the highest GWP among greenhouse gases.
Common Mistakes:
- Assuming methane or nitrous oxide have higher GWP than SF₆.
