Q
method
A
-use an immersion heater to raise temp of block by 20’c
-measure time taken to heat with a stopclock
-measure temp with with a thermometer
-measure mass of the aluminium block with a balance
-use joulemeter to measure the energy transferred to heater
-calculate using E=mass x specific heat capacity x temp change
