| A | B |

| Heat always travels from... | a higher temperature to a lower temperature |
| conduction | movement of heat through a substance without any movement of the substance |
| Good conductors | metal |
| Poor conductors (insulators) | glass and plastic; non-metals; liquids; gases |
| Why are gases poor conductors of heat? | The particles in a gas are too far apart. |
| convection | Heat is carried through liquids and gases by the movement of particles |
| What causes land and sea breezes? | convection currents |
| heat radiation | Heat travels in invisible rays without needing a substance to travel through |
| Good absorbers are... | good radiators |
| Bad absorbers are... | bad radiators |
| Good at absorbing and radiating heat. | Dark surfaces |
| What does tog value tell us? | The quality of insulation (the higher, the better). |
| How can heat be transferred?(RCCH) | Convection, conduction, radiation |
