Topic: Specific Heat Capacity

1. Remove the boiling tube of stearic acid from
   the water bath
2. Place the tube into a beaker of room
   temperature water
3. Add a separate thermometer to the water
4. Take readings from the thermometer in the
   stearic acid and the water every minute
   [Make sure to avoid parallax error while doing so]
5. Note readings in the table below
6. Note on the table when you observe the stearic
   acid change from a liquid to a solid.
7. Plot your results in a graph

Specific heat capacity:

• Amount of heat energy required to increase the temperature of 1kg of a substance by 1⁰
• Unit J/kg ⁰C

Change in thermal energy [J] = Mass [kg] x Specific heat capacity [J/kg ⁰C] x Change in temperature [⁰C] 

1. Set up the apparatus as shown the diagram.
2. Make note of all measurements: current (A), potential difference (V), mass (kg).
3. Use the electronic balance to measure the mass of your
4. Record the initial temperature of you block.
5. Switch on the heater and start your stopwatch.
   [You will now leave the heater on for 10 minutes]
6. While the heater is switched on take readings from the
   Ammeter and the Voltmeter.
7. Use these to calculate the Thermal Energy that will be
   supplied to the block in 10 minutes
8. Record the temperature of your block after 10 minutes.
9. Calculate the Change in Temperature
