Burning Fuels

ZIMSEC O Level Combined Science Notes: Experiment: Burning fuels

Aim: To burn and investigate the nature of fuels

Materials: methylated spirits/alcohol, candle, meths burner, bunsen burner, paraffin, tin lid or porcelain dish, tongs

Method

  1. Light a meths burner and observe the flame
  2. Burn a small amount of alcohol on a tine lid, holding the lid with tongs
  3. Light a candle and ty burning a piece of candle wax on the tin without a wick
  4. Burn a small amount of paraffin  on a tin lid

Observation and Results

  • Different fuels burn with different colours
  • Paraffin burns with a yellow flame
  • Wax also burns with a yellow/orange flame
  • Gas burns with a blue flame
  • Alcohol/Methylated spirit burns with a blue flame
  • Wax will not burn without a wick
  • Gas is the cleanest fuel as it produces the least amount of soot/smoke
  • It would be the most efficient fuel as all the carbon in it is utilized to produce energy
  • Alcohol burns without a wick but it produces a lot of soot/smoke

Conclusion

  • Different fuels burn with different friends
  • Some fuels will either not burn well or will not burn at all without a wick for example candle wax
