Question

what is the meaning of spontaneous combustion?​

Answer 1

Answer:

Spontaneous combustion, the outbreak of fire without application of heat from an external source. ... Oxidation gradually raises the temperature inside the mass to the point at which a fire starts.The likely explanation for suspected cases of spontaneous human combustion, then, is that there is an external source of ignition—a match, a cigarette, an electrical spark—that sets off the wick effect, but the evidence of it is destroyed by the fire.

Answer 2

Answer:

$Spontaneous \: combustion \: or \: spontaneous \: ignition \: is \: a \: type \: of \: combustion \: which \: occurs \: by \: self-heating \: (increase \: in \: temperature \: due \: to \: exothermic \: internal \: reactions), \: followed \: by \: thermal \: runaway \: (self \: heating \: which \: rapidly \: accelerates \: to \: high \: temperatures) \: and \: finally, \: autoignition.$
