RAPID COMBUSTION :-

When a substance bursts in a short span of time, the combustion of the substance is almost complete and a large amount of heat and light is produced. For example, LPG in a gas stove, oxyhydrogen flame used for welding, etc. Rapid combustion often occurs in the form of Fire.

SPONTANEOUS COMBUSTION :-

In this type of combustion, a substance catches fire as soon as its temperature reaches the ignition temperature. For example, White Phosphorus catches fire at room temperature of 35 degree Celsius and above without being introduced to any source of heat. The type of combustion in which material suddenly bursts into flames even without the application of heat is called spontaneous combustion.
