Why do fires need oxygen to burn?
ScienceChemistry
Quick Answer
Fire is a chemical reaction that depends on oxygen to keep fuel oxidizing rapidly. Without enough oxygen, combustion slows or stops.
The Full Story
Burning is a form of oxidation in which fuel reacts with oxygen and releases heat and light. That reaction must be hot enough to continue, creating the fire triangle: heat, fuel, and oxygen. If oxygen is removed, as in a sealed container or with a fire extinguisher, the flame goes out. This is why space does not support ordinary flames the way Earth’s air does, and why ventilation matters in homes and factories. Different fuels and oxygen concentrations can change how fast and how hot a fire burns.
Key Facts
1.Combustion requires heat, fuel, and oxygen
2.Fire extinguishers often work by removing oxygen or cooling the flame
3.Ordinary flames cannot persist without oxidizer
