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.
Fission happens because of chain reaction, and no chain reaction happens in fusion. In fission, the chain reaction happens due to the interaction between neutrons and fissile isotopes. Meanwhile, fusion occurs only under extreme temperature and pressure. Another difference between fission reactions and fusion reactions is that the energy from fission can be controlled but it cannot be controlled in fusion.
