  2. Fuel • Crude Oil is a fuel that is which take millions of years to make and gives us: • LPG - contains propane and butane, used in bottled cooking gas • Petrol- fuel for cars • Naphtha- used in the chemical industry • Paraffin- aircraft fuels • Heating oil - diesel and heating • Fuel oils - fuel for ships and power stations • Bitumen- surfaces for roads and roofs • To get these things we need to use a progress called Fractional distillation.

  3. Using carbon fuels • Oxygen is used for fuels to make energy. Complete combustion happens in a plentiful supply of air and incomplete combustion occurs when the supply of air is limited. Complete combustion releases more energy than incomplete combustion. Incomplete combustion also creates carbon monoxide, and more soot. Several factors must be considered when choosing the best fuel for a particular purpose. The fossil fuels include coal, oil and natural gas. Various factors need to be considered when deciding how to use a fossil fuel. These include: • The energy value of the fuel in kJ/g of fuel • The availability of the fuel • How the fuel can be stored • The cost of the fuel • The toxicity of the fuel - whether it is poisonous • Any pollution caused when the fuel is used, such as acid rain • How easy it is to use the fuel.
