Spontaneous ignition occurs when a material self-heats to a temperature high enough to cause combustion without an external ignition source. This phenomenon typically results from exothermic reactions within the material, such as oxidation, that produce heat faster than it can be dissipated.

Exothermic reactions are chemical processes that release energy, usually in the form of heat, to their surroundings, resulting in an increase in temperature. These reactions are crucial in various applications, from industrial energy production to biological processes like respiration.

Exothermic Reactions

Oxidation is a chemical process in which a substance loses electrons, often accompanied by a gain in oxygen or a loss of hydrogen. It plays a crucial role in various natural and industrial processes, including metabolism, combustion, and corrosion.
