A combustible material is a solid or liquid than can be easily ignited and burned. So we need 3 things for combustion to take place. They are:

1. Heat to reach the ignition temperature for the fire to start.
2. Fuel for the fire to burn.
3. Air to supply oxygen to the fire.

Ignition temperature is the lowest temperature at which a combustible substance catches fire. Fuel can be any combustible material. Oxygen is essential to keep the fire burning. Heat and light are given out.
