Answer 2

Combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame. The rate or speed at which the reactants combine is high, in part because of the nature of the chemical reaction itself and in part because more energy is generated than can escape into the surrounding medium, with the result that the temperature of the reactants is raised to accelerate the reaction even more.

A combustible material is a solid or liquid than can be easily ignited and burned. OSHA, DOT, and other federal regulations, apply specific technical definitions to this term. Combustible solids are those capable of igniting and burning. Wood and paper are examples of such material
