| Question | Answer |
|---|---|
| What is a mixture? | Combines two or more materials that retain their own properties. |
| What is a solution? | a mixture on which one material seems to disappear in another. |
| What is a crystal? | The solid phase of a material that forms in an identifiable shape or pattern. |
| What happens when a solid dissolves in a liquid? | The solid seems to disappear. |
| What happens when liquids evaporate? | they change into a gas and disperse into the air. |
| What results when a solvent has dissolved as much material as it can? | A saturated solution. |
| What refers to the amount of material that can dissolve in a given solvent? | Solubility |
| Solubility is different for different materials, what else can change it? | Temperature and different solvents. |
