Here's why:
* Combustion is a chemical process that involves the rapid reaction between a substance with an oxidant, usually oxygen, to produce heat and light.
* This reaction releases energy in the form of heat and light, which is why we see flames in a fire.
Examples of combustion reactions:
* Burning wood: Wood + Oxygen → Carbon Dioxide + Water + Heat and Light
* Burning natural gas: Methane + Oxygen → Carbon Dioxide + Water + Heat and Light
It's important to note that while oxygen is essential for most combustion reactions, some reactions can occur with other oxidants, like chlorine or fluorine. However, the term "combustion" generally refers to reactions with oxygen.
