5. Melting and Boiling Points

6. Melting and Boiling Points
The melting point is the temperature at which a substance changes from a to a
solid
liquid
The boiling point is the temperature at which a substance changes from a to a
liquid
gas
Water melts at .....°C and boils at °C.

8. Separation Techniques
A Mixture is formed from different substances that are not chemically joined together.
Some mixtures are insoluble eg Sand and Water
Some mixtures are soluble eg Salt and Water
