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 — ...

This is because good electrical conductors are usually good heat conductors too ... their performance as an ultrathin thermal insulator could be their most promising trait for future applications ...

Mmm, those look good! Metal is the best conductor ... This short film introduces pupils to conductors and insulators. It investigates how heat and electricity are transferred or not through ...
