Answer 2

Answer:

the ignition of organic matter (e.g. hay or coal) without apparent cause, typically through heat generated internally by rapid oxidation

Explanation:

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.
