4. Noble and base metals – 4.2 Conductivity of heat (tacher instruction)
Background information on the content and practical information on conducting the “Conductivity of heat" experiment.
Different metals have different thermal conductivities. The students should think about:
• In which metal technical devices is heat conduction important?
• Why do houses with a tin roof get hotter than houses with a tile roof?
• Why do frying pans often have wooden or plastic handles?
