Mixtures

There are two types of mixture

• Magnetic and separation

• Decantation and filtration

• Heterogeneous and homogeneous

• Heteregeous and evaporation

Filtration and evaporation are...

• A mixture of two substances.

• A homogeneous mixture.

• Methods to separate the components of mixtures.

• A physical combination.

We can use decantation ...

• to separate mixtures of liquids and solids.

• to remove small particles.

• to form a solution.

• to separate liquids.

If we dissolve salt in water and heat the water,it becomes a vapour and leaves the salt. This is called

• Decantation

• Evaporation

• Filtration

• Distillation

Matter existin three main states...

• Reversible, irreversible and volume

• Mass, density and volume

• Solid, liquid and gas.

• Physical, chemical and irreversible

The atoms in liquid water are...

• Close together but move do not move around much

• Close together but move around freely

• Further apart

• Gases .

The amount of matter that an objets¡ contains is

• Volume

• Density

• Gass

Physical changes can be...
