Conduction, radiation and convection
- Conduction
- How is works: As the tempersture of a
solid is increased, the particles vibrate
more, so they gainmore kinetic energy.
- The increase in kinetic energy is passed onto
adjacent particles through collision causing
them to vibrate more.

- Conduction in Metals
- Metal atoms exist as positivly charged metal ions in a
regular lettice structure. The ions are surrounded by
negativley chaqrged electrons.
- some of the electrons are effectivley freeand can
move within the metal.

- Convection
- Convection occurs only in fluids (liquids and gases). as a fluid is heated the particles gain energy
