3.4) The student calculated the specific heat capacity of aluminium to be 2 390 J/kg °C.
The ‘true’ specific heat capacity of aluminium is 900 J/kg °C.
Suggest why the student’s result for aluminium is different from the ‘true’ value. [2 marks]
3.5) The teacher suggested that putting bubble wrap round the metal block would change the results.
How would using bubble wrap change the results?
Give a reason for your answer. [2 marks]
