Heated molecules are loosened, moving apart to form a gas. The gas molecules combine with oxygen in the air resulting in burning. The heat generated by the reaction is what sustains the fire. The heat of the flame will keep remaining fuel at ignition temperature.

A heat source is responsible for the initial ignition of fire, and is also needed to maintain the fire and enable it to spread..Heat allows fire to spread by drying out and preheating nearby fuel and warming and sorrounding air..
