1. Properties of Matter Creating a diagram that shows Melting and Boiling Points Complete each step in your Science notebook

2. Draw a line

3. Label it Solid, Liquid, and Gas Solid Liquid Gas

4. Insert lines at 0 degrees and 100 degrees Solid Liquid Gas 0 degrees 100 degrees

5. If you go to the right on the line you are adding energy to the molecules. If we add energy to Solid and get it hotter than 0 degrees we make it a Liquid. This is called melting Solid Liquid Gas 0 degrees 100 degrees Melting

6. If we go to the left on the line we are removing energy from the molecules. If we have liquid and remove energy to the point it is below 0 degrees we cross the freezing point and the water becomes ice Solid Liquid Gas 0 degrees 100 degrees Melting Freezing

7. So, 0 degrees Celsius is both the freezing and melting point of water. It just depends on if you are adding or removing energy as you cross the 0 degree temperature point. Solid Liquid Gas 0 degrees 100 degrees Melting Freezing

8. If we are adding energy as we cross 100 degrees we go from liquid to gas. This is the boiling point. Solid Liquid Gas 0 degrees 100 degrees Melting Freezing Boiling

9. If we are removing energy as we cross 100 degrees we go from gas to liquid. This is the condensation point. Solid Liquid Gas 0 degrees 100 degrees Melting Freezing Boiling Condensation

10. In Solids the molecules are packed together tightly and move very slow Solid Liquid Gas 0 degrees 100 degrees Melting Freezing Boiling Condensation

11. In Liquids the molecules are farther apart and sliding over each other. They have more movement than solids. Solid Liquid Gas 0 degrees 100 degrees Melting Freezing Boiling Condensation

12. In a Gas the molecules are spaced far apart and moving about quickly Solid Liquid Gas 0 degrees 100 degrees Melting Freezing Boiling Condensation

13. Interesting Facts Boiling and melting points are a physical property of matter Every substance in existence has a boiling and melting point Even diamonds have a melting and boiling point. When a diamond boils it turns into pure carbon dioxide gas

14. Your Task Create a poster sized drawing of the changing states of matter. If you email me a picture of your poster hanging on your bedroom wall or bathroom mirror I will give you 5 extra points on your next test. If you can’t send a picture you can bring in a note signed by your parent/guardian saying it is up there
