| Question | Answer |
|---|---|
| Solid | A substance with a define shape and volume |
| Liquid | A substance that has a define volume but not a define shape |
| Gas | A substance that has neither a define shape nor volume |
| Freezing | A change in state that occurs when the temperature of particles has decreased energy and a liquid turns into a solid |
| Melting | A change in state that occurs when particles speed up and change from a solid to a liquid |
| Boiling | A rapid change in state that occurs throughout a substance changing it from a liquid to a gas |
| Evaporation | A change in state that occurs as particles from the surface of a liquid change to a gas |
| Sublimation | A change in state directly from a solid to gas |
| Condensation | The reverse of evaporation when a substance changes from a gas to a liquid state |
| Deposition | The change in state directly from gas’s to a solid state |
| Boiling point | The specific temperature at which a liquid changes to a gas |
| Melting point | The specific temperature at which a solid changes to a liquid |
| What are the three phase changes | Solid / liquid / gas |
| Give examples of sublimation | Freezing/ melting/ evaporation |
| Periodic table | Groups/ periods/ locations/ division |
| Elements and compounds | Mixtures/ solutions / solvents / solutes |
