Give an brief explanation on the types of combustion with eg.
Dear student!
There are three main types of combustion as:
2.) Spontaneous combustion : It is the combustion in which substances burns without the application of any apparent cause is called spontaneous combustion. For example, sodium and phosphorus burn spontaneously in air, even when no external heat is provided to them.
1,) Rapid combustion : It is the combustion in which substances burn rapidly to produce heat and light is called rapid combustion. Here, external heat must be supplied to burn the substances. For example, when a burning matchstick is brought near a gas stove (with its knob turned on), LPG burns rapidly to produce heat and light.
3) Explosion : It is an uncontrolled combustion in which sudden reactions take place on ignition of some substances to produce heat, light, and sound. For example, fireworks on ignition produce heat, light, and sound.
