➢ Solids, liquids and gases can form mixtures.

Types of mixtures:

➢ Solid materials: Sand and rocks
➢ Solid and liquid: Salty water
➢ Liquid and liquid: Oil and water
➢ Gas materials: Atmospheric air

Properties of mixture:

➢ Mixtures are made of two or more substances that are physically combined together but
don't react.

➢ Each material in a mixture keeps its properties. For example:-
- Sugar doesn’t lose its sweetness when it is dissolved in water.
- In fruit salad, you can identify each type (taste) of fruit.
➢ The substances that form mixtures can be physically separated from each other.

1- Filtration: Can be used to separate a mixture if one material dose not dissolve in a

liquid (if one material has smaller particles than the other).
Example: Separating sand from (sand and water mixture).

:2- Evaporation Can be used to separate materials that evaporate at different
