Good and bad conductors of heat in physics

Good and bad heat conductors in physics are also used in everyday life. This happens completely automatically - whether in the household, the food industry or in the construction industry. It can therefore be interesting to learn more about thermal conduction.

1. Good heat conductors in everyday life

Good heat conductors in physics differ from bad heat conductors in that they have effective heat transfer. Good heat conductors are primarily metals: aluminum, copper, gold and silver. Copper is used in everyday life, among other things, for heating pipes, aluminum for cooking and baking pans.

2. Bad heat conductors in physics

Bad heat conductors in physics block or reduce physical heat exchange. Wood, paper, styrofoam, iron, glass, porcelain and stones such as marble or granite are poor heat conductors. These fabrics are traditionally used for thermal insulation or insulation. Cutlery handles, thermos flasks or facade insulation are in use thanks to this principle.

3. Liquids, gases, vacuum

Liquids and gases are fundamentally dependent on the ambient temperature in terms of their thermal conductivity - and thus neither a fundamentally good or bad heat conductor in physics. The higher the ambient temperature, the better the heat transfer. A second factor is the thermal conductivity of the solid to which the heat is to be transferred. A vacuum, on the other hand, is not conductive because it is self-contained. The food industry uses this principle to keep goods fresher longer.
