Question

1. which gas has a higher warming potential than carbon dioxide?

a. methane with high greenhouse properties
b. helium, a light atmospheric gas
c. oxygen used in combustion processes
d. nitrogen, which dominates the air

Explanation:

To determine which gas has a higher warming potential than CO₂, we analyze each option:

• Option a: Methane is a greenhouse gas with a much higher global warming potential than CO₂ (e.g., over 20 times higher over a century).
• Option b: Helium is not a greenhouse gas and has no warming potential.
• Option c: Oxygen is involved in combustion but is not a greenhouse gas and has no warming potential.
• Option d: Nitrogen is the main component of air and is not a greenhouse gas, so it has no warming potential.

Answer:

a. Methane with high greenhouse properties
