There are many variables which affect the ease of combustion. The degree of mixing with the air is a very large factor. Powdered coal dust in air will ignite explosively, while lumps of coal are much harder to ignite. Different compounds have different activation energies for combustion and there require different temperatures to ignite. Sometimes combustible materials are mixed with non-combustible materials which also makes them harder to burn; for example, dry paper burns quite well, but wet paper is very difficult to burn.

What is a combustible substance?
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.
What are non combustible substances. give examples?
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.
What is material that can burn called?
Material that can burn is called flammable material. It refers to substances or items that are easily ignited and capable of burning quickly and intensely when exposed to a heat source.
