In a similar manner, fire extinguishers are intended to remove one of the three components, such as water-based extinguishers that put out fires by eliminating heat and cooling the flames. During the chemical reaction that produces fire, fuel is heated to such an extent that (if not already a gas) it releases gases from its surface. The ancient Greeks believed that fire was one the four basic elements that composed all things in the universe.
