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
