Combustion is a chemical process that involves the rapid reaction between a substance with an oxidant, usually oxygen, to produce heat and light.
Here's a simplified explanation:
* Fuel: The substance being burned (e.g., wood, propane, gasoline)
* Oxygen: The oxidant that combines with the fuel
* Heat & Light: The products of the reaction, released as energy
While other substances can act as oxidants, oxygen is the most common one we encounter in everyday life.
