- Spontaneous burning
- Explosion
- Incomplete burning
- Rapid combustion
- None of the above
Answer [Detailed Solution Below]
Option 4 : Rapid combustion
The correct answer is Rapid combustion.
- Rapid combustion is a form of combustion in which large amounts of heat and light energy are released.
- This is used in a form of machinery, such as internal combustion engines, and thermobaric weapons.
Important Points
- Combustion or burning is a complex sequence of chemical reactions between a fuel and an oxidant accompanied by the production of heat or both heat and light in the form of either a glow or flames.
- Spontaneous burning is when a substance catches fire as soon as its temperature reaches the ignition temperature.
- White Phosphorus catches fire at room temperature of 35°C.
- Explosion combustion reaction that takes
place suddenly with the evolution of heat light and sound.
- In this case, a large amount of gas is evolved which gets liberated.
- When a cracker is ignited it suddenly reacts and bursts.
- Incomplete burning or combustion occurs when a combustion reaction occurs without a sufficient supply of oxygen.
- It releases less energy than complete combustion and produces carbon monoxide [a poisonous gas].
Key Points
- The burning of LPG is an example of rapid combustion.
- Hydrocarbon fuels can undergo complete combustion or incomplete combustion, depending on the amount of oxygen available.

What is a fast combustion reaction?
Explosive combustion reactions involve not only a reaction with oxygen, but also a chemical that promotes oxidation [oxidizing agent]. Because of this, the reaction is not limited by the amount of oxygen present and can occur quickly. The result is, well, explosive.
What causes rapid combustion?
Rapid Combustion requires external heat energy to start. This reaction results in enormous amounts of light and heat energy. As the name suggests this type of combustion occurs rapidly. Rapid combustion will take place as long as fuel remains.
What are the 3 types of combustion?
Combustion can be divided into three types – rapid combustion, spontaneous combustion and explosion.
What is spontaneous and rapid combustion?
Spontaneous combustionRapid combustionExplosionThe combustion in which substances suddenly burst into flames without the application of any apparent cause is called spontaneous combustion. The combustion in which substances burn rapidly to produce heat and light is called rapid combustion.
