Any solid material can be a heat “conductor.” Metals are good at conducting heat, similar to how they conduct electricity. To stop heat transfer, we need an insulator. The best insulator is a vacuum — ...

If you can’t answer the riddle, don’t feel bad. Metal conductors usually conduct electricity and heat. Usually, that’s true, but researchers at the Department of Energy’s Lawrence Berkeley ...

All they need now is somewhere to plug it in. This short film introduces pupils to conductors and insulators. It investigates how heat and electricity are transferred or not through different ...
