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 ...

are devices that switch as needed between roles as good thermal conductors and good thermal insulators. When one is installed in the heat-conduction path between a warm, heat-producing component and a ...

The particles of liquids are further apart than solids. This means that most liquids are poor conductors of heat because the frequency of collisions is reduced. The particles of gases are even ...
