Question

What is the difference between Spontaneous, rapid and explosion
type of combustion

Shveta Dua · Accepted Answer

Dear Student,
Here is the difference between spontaneous, rapid and explosion
type of combustion

Spontaneous combustion

Rapid combustion

Explosion

The 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 In rapid
combustion, external heat must be supplied so that the substances
can burn

The combustion in which sudden reactions take place on
ignition of some substances to produce heat, light, and sound is
called explosion

For example, sodium and phosphorus burn spontaneously in air,
even when no external heat is provided to them

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

For example, fireworks on ignition produce heat, light, and
sound

Hope this helps
Cheers!
