- Conduction & Convection
- Conduction
- Needs particles
- Works best in solids (particles close together)
- Gases are terrible as the particles are too far apart
- Particles gain energy and vibrate more
- They collide with one another and pass energy
- Can't travel through a vacuum
- Metals are great conductors because they have free electrons
- Convection
- Needs particles
- Can't travel through a vaccum
- CAN NOT TAKE PLACE IN SOLIDS
- Particles gain energy and move more, taking up more space
- Fluid becomes less dense so it rises
- When it reaches the surface it cools, becomes more dense and sinks
- Fluid becomes less dense so it rises
- Conduction
