Question

What is rapid combustion and spontaneous combustion?

Answer 1

Dear student,



Combustion :Combustion is a chemical process in which substances combine with oxygen in air, producing heat and light.Combustion is mainly of four types - explosion, spontaneous , Rapid and slow.

RAPID COMBUSTION : Rapid combustion is a process in which large amount of heat and light are released in a very short span of time.For e g - combustion of LPG, a candle or a spirit lamp which produces heat and light instantly.

Spontaneous combustion:

A certain minimum temperature is required to initiate combustion reaction. This temperature is called ignition temperature. When ignition temperature is lesser than the room temperature the reactants undergo combustion instantly as the ignition temperature has been met because of the higher room temperature. This type of combustion is called Spontaneous combustion.

Coal dust found in coal mines is very hazardous because of its ability to catch fire spontaneously.
