Learning outcomes Recall key words Determine the safe procedure to carry out the practical Evaluate your results

Specific heat capacity E = mass x SHC x change in temperature Mass = 1kg SHC Al = 900J/kg0C SHC Cu = 385J/kg0C

Specific heat capacity practical Equipment

Method Set equipment up, making sure to connect the power to the immersion heater Set the power pack to 12v Record the start temperature Turn the power on for 5 minutes, then switch power off Record the highest temperature reached Share results

Results table
