basic-science-quiz-for-beginners-08
  • Carbon
  • Oxygen
  • Nitrogen
  • None of these
That's Correct!
It's Wrong!

Fire cannot burn without oxygen because oxygen is necessary for the process of combustion. When a fire burns, it undergoes a chemical reaction called oxidation, in which the fuel combines with oxygen to release heat and light. Without oxygen, there is no source of matter to react with the fuel, and therefore, the fire cannot sustain itself. Carbon usually reacts with oxygen in a combustion reaction but does not undergo that reaction if oxygen is not present.
