  1. Combustion Reactions

  2. Combustion Reactions Aim: • To find out how much heat is in a candle. • One way to find out is to measure how much wax is burnt while raising the temperature of water in a test tube by say 200C.

  3. Materials & Method • Tea light candles • Thermometer • Retort stands with two clamps • Measure and record the mass of the candle. • Set the equipment up as shown and measure and record the temperature of the water. • Light the candle, and wait for the temperature to rise 10 or 20 0C. • Measure and record the new mass of the candle. • Calculate the change in mass of the candle. • Divide the temperature rise by the change in mass to give a value with units of 0C/g wax • Compare your results with the rest of the class. Safety Considerations

  4. Results Other Observations
