Why do flames need oxygen to burn?
ChemistryCombustion
Quick Answer
Combustion needs oxygen because it is the oxidizer in most everyday fires. Oxygen lets fuel molecules release energy by forming more stable products like carbon dioxide and water.
The Full Story
Fire is a rapid oxidation reaction, and in ordinary conditions oxygen from the air is the most common oxidizing agent. When fuel burns, chemical bonds are rearranged into products such as carbon dioxide, water, and ash, releasing heat and light. Without enough oxygen, combustion slows or stops. This is why smothering a fire with a lid, blanket, or foam can help extinguish it.
Key Facts
1.Combustion is an oxidation reaction
2.Air supplies about 21% oxygen
3.Smothering a fire can cut off oxygen
