Substances that don’t burn in the presence of air are called non-combustible substances. E.g. Glass, stones

Inflammable substances are those which have low ignition energy. They catch fire easily and highly combustible in nature. Inflammable substances have higher vapour pressure which makes them more flammable. Some examples of inflammable substances are: Alcohol, kerosene, benzene.

Oxygen gas / ignition temperature supports the combustion of fuels. For example, cooking gas and producer gas are fuels that burn in the presence of oxygen gas

Those substances catch fire easily which undergoes combustion or burn are called combustible substances. ( need the low temperature to burn). For example Paper, cloth, cooking gas (LPG), CNG, Kerosene oil, wood, charcoal, etc.

The chemical process in which a substance reacts with oxygen to give off heat is called combustion. Examples are ethane, wood, propane.

a chemical reaction between two compounds that results in the interchange of one part of each to form two different compounds, as in AgNO3 + KI → AgI + KNO3

Chemical displacement is a reaction in which more reactive elements displaces the less reactive elements from their compounds

A decomposition reaction can be defined as a chemical reaction in which one reactant breaks down into two or more products

a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).

A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products
