• A reaction or process that releases heat energy

  Exothermic

• Combustion is when a substance burns, it reacts with oxygen
• Complete combustion is when a substance burns with a plentiful supply of oxygen, producing $CO_2$ and $H_2O$
• Incomplete combustion is when a fuel burns with a limited supply of oxygen, producing carbon monoxide and soot
• A metal can and draught shield are used to keep in the heat
