Fire is the heat and light energy released during a chemical reaction, in particular a combustion reaction. Depending on the substances alight, and any impurities within, the color of the flame and the fire intensity might vary. Chemistry Flaming Fires which is ignited prior to consumption.]]Flaming fires involve the chemical oxidation of a fuel (combustion or release of energy) with associated flame, heat, and light. The flame itself occurs within a region of gas where intense exothermic reactions are taking place. An exothermic reaction is a chemical reaction whereby heat and energy are released as a substance changes to a more stable chemical form (in the case of fire, usually generating carbon dioxide and water). As chemical reactions occur within the fuel being burned, light and heat are released. Depending upon the specific chemical and physical change taking place within the fuel, the flame may or may not emit
