Spontaneous combustion: The ignition of a substance or body from the rapid oxidation of its own constituents without heat from any external source is known as spontaneous combustion.
Example:

  1. Phosphorous and sulphur start burning instantaneously; at room temperature.
  2. In coal mines, fire breaks out many a times because of combustion of coal dust.

Rapid combustion: Rapid combustion is a form of combustion in which large amounts of heat and light energy are released.
Example:

  1. Matchstick burns rapidly on being struck against the sides of a matchbox.
  2. Combustion of natural gas, LPG, petrol etc.

Explosion: When combustion is accompanied by sudden production of heat, sound and large amount of gas, it is called explosion.
Example:
Firecrackers and bombs are substances which show explosion.
