Conduction in non-metals:

### Teaching Notes:

0:00 - 0:02:

- before being heated, particles in the solid are vibrating about their fixed position.

0:02 - 0:22:

- when heated, the thermal energy is converted to kinetic energy, causing particles to vibrate more vigorously about their fixed positions.

- they collide with neighbouring particles, transferring some of their kinetic energy to them

Conduction in metals:

### Teaching Notes:

0:00 - 0:02:

- before being heated, atoms in the metal are vibrating about their fixed position

- delocalised electrons are able to move across the solid

0:02 - 0:22:

- when heated, the thermal energy is converted to kinetic energy, causing particles to vibrate more vigorously about their fixed positions.

- metal atoms collide with neighbouring particles, transferring some of their kinetic energy to them

- delocalised electrons gain kinetic energy and move across the solid, colliding with other electrons and atoms in the process

- the collisions result in a transfer of kinetic energy
