Energy Required Practicals

Specific Heat Capacity Practical

1
Equipment Setup
  1. Place an empty beaker on a balance
  2. Tare the balance to zero
  3. Pour oil into the beaker
  4. Record the mass of the oil from the balance
2
Further Setup
  1. Using a thermometer, record the initial temperature of the oil
  2. Place an immersion heater into the oil
3
Even more setup
  1. Wrap the beaker in insulating foam
4
Measurements
  1. Connect the immersion heater to a joulemeter
  2. Connect the immersion heater to a powerpack
  3. Turn on the powerpack
  4. Leave for 30 minutes
  5. Record the final temperature from the thermometer
  6. Record the energy transfer from the joulemeter
  7. Calculate the specific heat capacity using the shc equation






Thermal Insulators Practical

1
Equipment Setup
  1. Place a small beaker inside a large beaker
  2. Add boiling water to the small beaker
  3. Place a cardboard lid over the large beaker, ensure that the lid has a hole in it
  4. Put a thermometer in the hole of the lid
  5. Record the initial temperature, and then rerecord the temperature every 3 minutes for 15 minutes
2
Testing Insulators
  1. Repeat the experiment using the same volume of boiling water, this time place an insulating material in the large beaker
  2. Repeat the experiment many times, using different insulating materials of the same mass
