Energy and Fuels

You can measure the amount of energy produced when a fuel is burnt by using a calorimetry (burning the fuel and using the flame to heat up water)


  • Put 50g of water in the copper can and record its temperature
  • Weight the spirit burner and lid
  • Put the spirit burner under the can and light the wick
  • Heat the water, stirring constantly, until the temperature reaches about 50`C
  • Put out the flame and measure the final temperature of the water
  • Weigh the spirit burner and lid again

How to work out energy per gram:

  • Mass of spirit burner + lid before heating = 68.75g
