What is combustion?

Combustion is defined as a rapid chemical reaction between a fuel and oxygen, resulting in the production of heat and light. This process typically involves the transformation of a hydrocarbon fuel (like wood, gasoline, or natural gas) reacting with oxygen in the air. During combustion, energy is released in the form of heat, and this is often observable as flames. Additionally, combustion can produce byproducts such as carbon dioxide and water vapor, depending on the type of fuel and the completeness of the reaction.

This definition encompasses the essential characteristics of combustion, highlighting its rapid nature and the requirement for oxygen, which significantly distinguishes it from other types of chemical reactions, such as the slow reactions between solid elements or processes that might not involve oxygen. Understanding combustion is fundamental in areas such as energy production, engines, and fire science.
