1

Conduction

(Solids) vibrating particles pass on extra kinetic energy (heat) to neighbouring particles

2

Convection

(liquids and gases) liquid and gas particles are free to move. Particles with more kinetic energy move from hotter to cooler regions taking their thermal energy with them.

3

Radiation

Heat energy travels in waves
Doesn't need particles

4

Good conductors

Metals are good conductors of heat. Copper is one of the best and is used in wiring and pipes

5

Poor conductors

Plastics, polystyrene and air are poor conductors and are used as insulators to keep heat in.

6

Evaporation

Process by which a liquid becomes a gas. Evaporation takes thermal energy away from the surface on which it is occurring
Particles move further a part due to more kinetic energy

7

Condensation

Process by which a gas becomes a liquid
Particles move closer together they have less kinetic energy

8

Latent heat

Change in state but no change in temperature
