| Question | Answer |
| What is another word for thermal in, for example, thermal conduction? | Heat |
| Which method of thermal transfer works best in solids? | conduction |
| What have metals got that makes them better at thermal conduction? | free (or delocalised) electrons |
| Why are liquids and gases both called fluids? | They can flow. |
| Which method of thermal transfer works best in fluids? | convection |
| What is another name for thermal or heat radiation? | Infra Red |
| Which type of thermal transfer is the only one that works in a vacuum? | radiation |
| What is the opposite of a conductor? | insulator |
| One word for bouncing radiation off a surface. | reflection (or reflecting) |
| One word for soaking up thermal radiation. | absorbing (or absorption) |
| One word for hot things giving off thermal radiation. | emitting (or emission) |
| Best kind of surface for reflecting: | shiny (glossy) and light |
| Best kind of surface for absorbing: | dark and dull (matt) |
| Best kind of surface for emitting: | dark and dull (matt) |
| Best insulator in the universe and why: | vacuum (no particles) |
| Best insulator between free air and trapped air and why: | trapped air (trapping it stops convection currents) |
| Kind of window that uses trapped air for insulation: | double glazing |
| In a solid that is heated atoms and molecules.. | .. vibrate more, and get further apart. |
| In a fluid that is heated atoms and molecules.. | .. move faster and get further apart. |
| Density equals | mass divided by volume |
| If its particles get further apart a fluid's density gets | less (smaller, lower) |
