Origin

Combustion is a chemical reaction between a fuel and an oxidizing agent, typically oxygen, that produces heat and light. This reaction involves the rapid oxidation of the fuel, releasing energy in the form of heat and often producing flames.

To define combustion, you can follow these steps:

1. Identify the elements involved: Combustion involves a fuel and an oxidizing agent, usually oxygen.
2. Understand the process: Combustion is a chemical reaction in which the fuel reacts with the oxidizing agent, releasing energy in the form of heat and often light.
3. Note the products: The products of combustion depend on the specific fuel, but common products include carbon dioxide (CO2), water (H2O), and sometimes carbon monoxide (CO) or soot.
4. Recognize the signs: Combustion is often characterized by the presence of flames, heat, and light.
5. Consider the applications: Combustion is used in various applications, including heating, cooking, transportation, and power generation.

By following these steps, you can define combustion and gain a deeper understanding of the process.
