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 ...

Scientists in the US have developed a polymer thermal conductor that they claim can dissolve heat instead of insulating it. Plastics are already good insulators because they can trap heat easily ...

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 ...

A semiconductor is a material or device that only conducts electricity under certain conditions. Some elements in the periodic table, such as carbon, silicon, and germanium, are intrinsic ...
