Combustion is a chemical process in which a substance reacts with oxygen, releasing heat and often light in the form of flame. It is a highly exothermic reaction, meaning it releases a significant amount of energy. Combustion is a fundamental process in many natural and industrial settings, including the burning of fuels for energy, the metabolism of organisms, and the formation of stars.

The process of combustion typically involves three main components: a fuel, an oxidizer, and heat. The fuel is the substance that undergoes combustion, while the oxidizer is usually oxygen from the air. Heat is required to initiate the reaction and sustain the combustion process. Once combustion begins, it can continue as long as there is a supply of fuel and oxygen.

Combustion can occur in various forms, including rapid combustion, smoldering, and spontaneous combustion. Rapid combustion, often referred to as burning, is a rapid oxidation process that produces heat and light. Smoldering, on the other hand, is a slow combustion process that occurs without a visible flame. Spontaneous combustion refers to the self-heating of a substance until it reaches its ignition temperature, causing it to burn.

Combustion plays a crucial role in many aspects of daily life and industry. It is used to generate electricity, power vehicles, and heat homes. In nature, combustion is responsible for the energy released during the metabolism of food in living organisms and the formation of stars through nuclear fusion. However, combustion also poses significant risks, including the release of harmful pollutants and the potential for explosions and fires. Therefore, understanding and controlling combustion processes are essential for both practical applications and safety measures.
