GCSE Physics

Conduction in Non-Metals

Every atom is physically bonded to its neighbours in some way. If heat energy is supplied to one part of a solid, the atoms vibrate faster.

As they vibrate more, the bonds between atoms are shaken more. This passes vibrations on to the next atom, and so on:

conduction of heat through a solid

Eventually the energy spreads throughout the solid. The overall temperature has increased.
