Worked Solution & Example Answer:A student set up the experiment shown below to investigate heat conduction - Junior Cycle Science - Question a - 2011
Step 1
Suggest a suitable substance to use in the experiment to stick the pins on the ends of the rods.
Answer
A suitable substance to use in the experiment is wax or petroleum jelly (vaseline). These substances can effectively hold the pins in place while allowing for the observation of heat conduction.
Step 2
What does this result tell you about copper?
Answer
The result showing that the pin on the copper rod was the first to fall off indicates that copper is the best conductor of heat. This means that it transfers heat rapidly, causing the wax or petroleum jelly holding the pin to melt faster.
