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.

- 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.
