Answer 2

The chemical process in which a substance reacts with oxygen to give heat is called combustion.

• The substances which are combusted are called combustible substances.
• It can also be called fuel.
• Sometimes, in the form of a flame or as a flame, during combustion, light is accompanied by heat.
• Why does a fire go out when water is poured on burning wood?
• This is because water absorbs large amounts of heat energy, resulting in the temperature of the wood falling below its ignition temperature and extinguishing the fire.
