Energy content is an important property of fuels. This property helps scientists and engineers determine the usefulness of a fuel. Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g).

You can determine the energy content of a fuel by burning an amount of the fuel and capturing the heat released in a known mass of water in a calorimeter.


  • Use a temperature probe to measure temperature.
  • Use a balance.
  • Determine energy content.
  • Compare the energy content of different fuels.
