A fire needs 3 things: Fire 27/05/2016 Fuel Oxygen Heat The Fire Triangle
27/05/2016 When something is burned a chemical reaction occurs between the fuel and oxygen: Magnesium + oxygen Magnesium oxide Carbon + oxygen Carbon dioxide
Keywords: Combustion (burning) – A chemical reaction between a fuel and oxygen – Makes heat, light and other products Fuel – Any material that releases energy when burned Vapour – Many small particles of liquid in the air Ignition – starting combustion
Fuels 27/05/2016 A “fuel” is something that can be burned to release heat and light energy. The main examples are: Coal, oil and gas are called “fossil fuels”. In other words, they were made from fossils.
FIRE & FUELS: TRUE or FALSE? 1)A fuel always produces heat when it combusts 2)All fuels are solids 3)In a car, chemical potential energy in transformed into kinetic energy 4)A fuel, supply of oxygen and a source of ignition are needed for combustion 5)The source of oxygen for most combustion is the air 6)Most fuels are compounds containing carbon 7)The energy stored in nearly all fuels originally came from the moon TRUE FALSE, they can be gas and liquid also TRUE FALSE, came from the sun
