GCSE Combined Science · key term
The ability of a material to transfer energy through itself by heating.
Used by AQA and Edexcel
Specification 5.1.2.3 · Paper 3
Revise: Metals and Non-MetalsCopper conducts electricity well and can be drawn into wires, so it is used in electrical cables. Its good thermal conductivity also makes it useful for saucepans. Gold's lustre and resistance to corrosion make it suitable for jewellery.
Paper 5, Paper 6
A measure of how readily a material transfers energy by conduction. A material with lower thermal conductivity is a better thermal insulator.

Lower thermal conductivity means energy passes through the wall material less readily, so the building cools more slowly.
