Fire is a chemical ______ known as combustion.

Explanation:
Fire is a chemical reaction, specifically combustion. Combustion is a rapid oxidation of a fuel that releases heat and light. In this process, the fuel reacts with an oxidizer (usually oxygen in the air), bonds in the fuel break, new bonds form, and energy is released as heat—often with a visible flame. This makes fire the chemical change behind burning, not just a vague event or phenomenon. The exact products vary (carbon dioxide and water in complete combustion; carbon monoxide or soot in incomplete combustion), but the core idea remains: burning is a chemical reaction.
