Solution:Concept- Rapid combustion is a process in which large amounts of heat and light are released in a very short span of time.
Chemical reaction known as combustion occurs when a material combines with oxygen in the air generating light and heat. There are three primary types of combustion: rapid, spontaneous, and explosive.
Rapid combustion- A form of combustion called rapid combustion releases a lot of heat and energy.
Examples include burning a match or burning LPG.
Spontaneous Combustion – The type of combustion in which a material suddenly ignites, without any apparent cause, is called spontaneous combustion. E.g. burning phosphorus.
Explosion- When a sudden reaction takes place with the release of heat and light and a large amount of gas is evolved, it is called an explosion. For example firecrackers.
Hence, rapid combustion is the correct answer.
