Spontaneous combustion. Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition.
A combustion reaction is when a substance reacts with oxygen and releases a huge amount of energy in the form of light and heat. A combustion reaction always has oxygen as one reactant.The second reactant is always a hydrocarbon, which is a compound made up of carbon and hydrogen. combustion reaction is when a substance reacts with oxygen and releases a huge amount of energy in the form of light and heat.
