Burning fuels investigation


My aim is to find out which fuel releases the most energy per mole measured by heating water.


In this investigation I will burn alcohols to heat up a beaker of water. I will be burning five fuels which are called Methanol, Ethanol, Propanol, Butanol and Pentanol. In my investigation I predict that the alcohol Pentanol would release more energy than the other alcohols because as the chain length of the alkanes get longer, the more energy is released.


  • Retort stand
  • Clamp
  • Measuring cylinder
  • Thermometer
  • Heatproof mats
  • Copper can
  • Splint
  • Chemicals(Methanol, Ethanol, Propanol, Butanol and Pentanol)

Independent variables

  • Using the same scales
  • Same amount of water in copper beaker
  • Same height of thermometer from water
  • Temperature of water before experiment
  • Weight of alcohol before experiment

Fair Test

To make it a fair test:

  • I made sure I put the same amount of water in the copper can.
  • I made sure that the water started with the same temperature with the same alcohol.
  • I made sure that the height was the same from the water to the thermometer.
