Question
Describe an experiment to show that heat is conducted through a metal rod. Is there any material movement of the rod?
Answer
Experiment
Take a rod or flat strip of metal. Fix a few small wax pieces on the rod. These pieces should be at nearly equal distances. Clam the rod to a stand or place one end of the rod in between two bricks. Heat the other end of the rod with a candle.
Observation
The heat from the candle side passes towards the other end by dissolving wax pieces on the rod.
Conclusion
This experiment shows that heat is transferred from the hotter end to the colder end.
There is no material movement of the rod.
