A. Two metal blocks, one made of copper and
one made of aluminium.
B. Using scales find out the mass off both
blocks.
C. Use two thermometers and a stopwatch.
D. Measure the temperatures of both metal blocks and write it down in the results
table as “the temperatures at the start”.
E. Use two
identical electric heaters and using
the same amount of electricity heat up both the copper and aluminium blocks
for 5 minutes.
Results
