Conduction, radiation and convection
1 Conduction
1.1 How is works: As the tempersture of a solid is increased, the particles vibrate more, so they gainmore kinetic energy.
1.1.1 The increase in kinetic energy is passed onto adjacent particles through collision causing them to vibrate more.
2 Conduction in Metals
2.1 Metal atoms exist as positivly charged metal ions in a regular lettice structure. The ions are surrounded by negativley chaqrged electrons.
2.2 some of the electrons are effectivley freeand can move within the metal.
3 Convection
3.1 Convection occurs only in fluids (liquids and gases). as a fluid is heated the particles gain energy
