Answer 2

|| Combustion ||

A chemical process in which a substance burn in oxygen (of air) to give off heat and light (which may or may not be produced) is called combustion. Burning of Magnesium and Charcoal are the example of combustion. Since both give heat and light on burning. Thus they both are combustible in nature. It is not essential that light must be produced in Combustion.

|| Types of Combustion ||

Depending upon the condition under which combustion take place there are three types of combustion - rapid combustion, spontaneous combustion and explosion. Let us study these types of Combustion in detail.

Rapid Combustion : When a combustible substance burns at the rapid rate producing a very large amount of heat and light in a short period of time it is called rapid combustion.

Spontaneous combustion : When a combustible substance burns on its own without the help of any external heat it is called spontaneous combustion.

Explosive combustion : Combustion reaction that takes out suddenly without evolution of a large amount of gases, heat ,light and sound is known as explosive combustion.
