Rapid Combustion⚠️

Combustion in which a substance burns rapidly and produces heat and flame is known as rapid combustion, such as combustion of natural gas, LPG, petrol etc.

This is usually attained by introducing external heat. Substances which undergo rapid combustion have lower ignition temperature.
