Flammability or ability to burn refers to a property of a
material to combine with oxygen and form an oxide. When a substance burns it is always
accompanied with a release of energy, usually in the form of
heat.

For example when a hydrocarbon burns, the carbon in
the compound combines with oxygen to form carbon dioxide and the hydrogen combines with
oxygen to form water. The temperature at which substances burn varies and many are not
flammable as they do not require to form an oxide to achieve a lower energy
state

chemical property that determines whether a substance will react or burn in the presence
of oxygen.
