To make a fire you need a fuel (wood, coal, or anything flammable), oxygen and heat. If you have all these things then you can create a fire, usually we do this by applying heat to the fuel in the presence of oxygen in the air. When the fuel is hot it starts to react with oxygen in the air to form carbon dioxide and other gases – the reaction is exothermic so it provides more and more heat to keep the fire going. The fire will keep buring until there is no more fuel or there is not enough oxygen left!
