What examiners said
Many candidates gave answers that included atoms vibrating and that these vibrations are passed onto the next atom. Fewer candidates gave answers that included the transfer of free electrons.
— Examiner report, October/November 2023, 0973/41 Q9(d) (Cambridge)
Candidates need to ensure that they understand the process of thermal conduction and can explain it. Many candidates used the terms particles and electrons interchangeably. Often candidates stated that increased thermal energy would cause the particles to start to move rather than increase the speed of their vibration. Several candidates referred correctly to delocalised electrons but fewer were a...
