Liquids and Gases.

• Liquids
• Liquids cannot be compressed.
• Liquids flow.
• A liquid takes the shape of its container.
• The volume of the liquid stays the same.

• Gases.
• Gases can be compressed easily.
• Gases flow .
• A gas takes the shape of the whole of a
  container.
• A gas has no definite volume.

4
Solids.

• Solids cannot be compressed.
• Solids do not flow.
• The shape of a solid always stays the same.
• The volume of a solid stays the same.

5
Separating.

• A solution is formed when sugar is dissolved in
  tea.
• Too much sugar and it becomes saturated.
• Things that dissolve are called soluble.
• Things that dont dissolve are called insoluble.
• The sugar can be recovered by evaporation.

6
Filtering.

• Filtering is when you recover the solid from the
  liquid.
• E.g Coffee.
• Coffee is filtered to remove suspended solids.

7
Decanting.

• If you have water and sand and you pour the water
  off that is called decanting.
• Condensation.
• Condensation is when steam turns back into liquid.

8
Molecules.

• Everything is made out of atoms.
• A molecule is two or more atoms joined together
  E.g Water.
• H20 consists of two hydrogen atoms and 1 oxygen
  atom.

9
Dilution.

• When you add water to things they become diluted
  or weaker.
• They are said to be less concentrated .
