Why Does Fire Need Oxygen ?
Fire is a combustion reaction. Fuel, heat, and oxygen are needed for combustion. Oxygen helps the fuel react and release energy. This reaction produces heat and light. If oxygen is removed, the reaction slows and stops. That is why flames go out when covered.
Words: i. Heat, ii. Fuel, iii. Oxygen, iv. Combustion, v. Flame goes out
Key Point: Fire needs oxygen because combustion cannot continue without it.
