Question

What is ingious temperature?

Answer 1

Ignition temperature is the minimum temperature to which a combustible substance must be heated, before it catches fire.

Therefore, we see that a combustible substance cannot catch fire as long as its temperature is lower than its ignition temperature

Example :

• A match stick can not burn on its own unless it rubbed on the hard surface.
• A piece of paper can not burn on its own unless it is lighted with a match stick.
• A log wood can not burn on its own unless it is lighted with kerosene oil to start the fire.
