The substances that can react with oxygen and give out heat and light i.e., undergo combustion are called combustible substances.
Combustible substance : Substances that burn easily or catch fire easily are called combustible substances. Paper, clothes, wood, LPG are all combustible substances. Without these substances, a fire cannot be started.
Substances which undergoes burning is combustible substances. eg: paper ,cloth , wood substances which doesnt undergoes burning is non_combustible substances. eg: stone, bricks soil ,water. So, paper is combustible .
Something that burns is called combustible Substances that burns in air or oxygen to produce heat and light are called combustible substances
Cobustible substances can catch on fire but non-combustible substances are inflammabe
Another term is flammable.
A substance which has ability to burn is called combustible.
Capable of igniting and burning is a combustible gas. Any compressed gas meeting the requirements for lower flammability limit, flammability limit range, flame projection,etc. All flammable substances are surely combustible, but all combustible substances are not essentially flammable.
Non-combustible substances are materials that do not burn or catch fire under normal circumstances. Examples of non-combustible substances include metals like steel and aluminum, as well as materials like concrete, stone, and glass. These substances have high melting points and do not release flammable gases when exposed to heat or flames, making them resistant to combustion.
No, many are not. Especially those, such as carbon dioxide and water, that are products of combustion.
the substances which have very low ignition temperature and can easily catch fire with a flame are called inflammable substances.Examples are petrol,alcohol,L.P.G etc.
There are some simple requirments for something to be a convenient fuel - it must be abundant, easily collected and transported, cheap and ideally have a high calorific value per unit volume. Actually the question asked is wrong. Combustible subs. = Combustible materials all combustible subs./combustible materials are fuel but all fuel are not combustible subs/combustible material because fuel can also be an incombustible material/incombustible subs.
i think it is not a combustible substance because it doesn't produce heat. ******************************************* No, examples of combustible substances are wood, paper, petrol, flour dust, etc. Iron will never burst into flames, though it will melt into a liquid if heated enough.
