GCSE Combined Science · key term
The transfer of energy from a hotter region to a cooler region through a material, without the material flowing as a whole.
Used by AQA
Specification 5.2.2.8 · Paper 3
Revise: Metals as ConductorsThermal conduction transfers energy from a hotter region to a cooler region. When one part of a metal is heated, delocalised electrons there gain energy. Because they can move through the structure, they carry energy away from the heated region and transfer it to other particles through interactions.
For thermal conduction, state that delocalised electrons transfer energy through the metal. Saying only that electrons move does not complete the explanation.
