Flammability - GCSE Chemistry Definition

Flammability is a term used to describe how easily a material can catch fire and burn. In chemistry, it refers to the ability of a substance to ignite when exposed to a flame or spark. A highly flammable substance will catch fire and spread quickly, while less flammable materials will burn more slowly or may not burn at all. Understanding flammability helps us handle materials safely, prevent fires, and choose the right substances for different uses. For example, petrol is considered highly flammable, whereas water is not flammable at all.
