What actually burns in a fireWhat actually burns in a fire

Often a misconception is fire burns the actual chair or Often a misconception is fire burns the actual chair or piece of wood. It is the gasses given off by an object piece of wood. It is the gasses given off by an object that burns. Heat causes objects to give off these that burns. Heat causes objects to give off these flammable gasses.flammable gasses.

When the gasses reach their ignition temperature you When the gasses reach their ignition temperature you see the light given off during the oxidation known as see the light given off during the oxidation known as fire. Fire itself generates more heat to the object and fire. Fire itself generates more heat to the object and thus an endless cycle begins until all of the gasses thus an endless cycle begins until all of the gasses have been exhausted from an object. Then the have been exhausted from an object. Then the remaining particles or ash are what is left.remaining particles or ash are what is left.
