1. Combution:-
Combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
2.Ignition temperature
the lowest temperature at which a combustible substance when heated (as in a bath of molten metal) takes fire in air and continues to burn
— called also autogenous ignition temperature
3.Rapid Combustion
Rapid Combustion is a form of combustion , otherwise known as fire, in which large amounts of heat & light energy are released, which often results in a flame.
Example :- Burning of matchstick, Combustion of LPG.
4.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.
5.Explosion
An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases.
