Which gas in the atmosphere helps combustion?
Answer and explanation
Correct answer: Oxygen
Oxygen supports combustion by reacting with a fuel when sufficient heat is present. It is not itself the fuel, but it enables the chemical oxidation that releases heat and keeps a flame burning. Nitrogen, argon and helium are generally non-supportive or largely unreactive in ordinary burning conditions, so they do not maintain combustion in the way oxygen does.
