Worked Solution & Example Answer:Copper, aluminium and iron rods are set-up as shown in the diagram - Junior Cycle Science - Question b - 2009
Step 1
What conclusion can be drawn from this observation?
Answer
The experiment demonstrates that the metal ball falls from the copper rod first due to its superior thermal conductivity. This indicates that copper is the best conductor of heat among the three materials tested (copper, aluminium, and iron). Therefore, we can conclude that:
- Copper is the best conductor of heat compared to aluminium and iron.
- Aluminium conducts heat less effectively than copper but better than iron, which conducts the least effectively among the three.
