- Methods of transferring energy.
- Conduction
- 1) When particles in a solid are given more energy they vibrate
- 2) They collide with neighbouring particles, which causes them to vibrate
- 3) The energy continues to spread across the solid
- In metals there are free electrons which means they are good conductors
- Convection
- 1) Particles in a liquid or a gas are given energy which causes them to spread out
- 2) The density is lower so the hot materials rises.
- 3) The hot material is replaced by cold material, which creates a convection current
- Evaporation
- The particles on the top of a liquid move the fastest when they are heated up.
- The particles escape from the liquid as a gas
- Condensation
- If energy is transferred from particles in a gas the particles will form droplets
- This is called condensation
- Conduction
