Ans: It is the burning of a chemical substance in presence of oxygen. In combustion carbon dioxide along with water vapor releases. Heat also releases during combustion reaction. So combustion is exothermic in nature.
Different types of combustion are:
a) Spontaneous combustion
b) Rapid combustion
c) Explosion
d) Slow combustion
(a). Spontaneous combustion:
A substance burns without the support of external reagent is called spontaneous combustion.
Ex: when white phosphorus kept open atmosphere it burns immediately.
(b).Rapid combustion:
A substance that burns quickly and producing heat is called rapid combustion.
Ex: Burning of candle
(c). Explosion:
If burning of substance produces lot of heat then it is called explsion.
Ex: burning of crackers.
(d). Slow combustion:
The combustion reactions which take place slowly and give less amount of heat slowly are termed as slow combustion reactions.
The processes of rusting, digestion of food are examples for slow combustion
