9. Homework : Venn Diagram

10. Warm Up In your science journals answer the following questions:
Would you rather be an amorphous solid or crystalline solid? Explain why.
How would you determine if a liquid had high viscosity or low viscosity? What is the difference between the two?

11. Today we will analyze the states of matter using Cornell Notes, task cards, and vocab maps

12. 1. States of matter 2. Liquids 3. A type of fluid – what is it?
4. a substance that flows.
3.Particles are about the same distance apart
3. A gas can also be a fluid

13. 4. Surface tension – what is it?
3. Properties of liquids
4. Surface tension – what is it?
5. result of an inward pull among molecules of a liquid that brings the molecules on the surface closer together
5. Surface acts like a skin
5. Examples
6. bug walking on water

14. Google images

15. 4. Viscosity – what is it?
5. liquids resistance to flowing
5. depends on the size and shape
5. high viscosity = flow slowly
6. Honey
5. low viscosity = flow quickly
6. Water

16. HW Create a vocab map for each of the following terms 1. Fluid
2. Surface tension
3. Viscosity

17. Today we will
Compare and contrast the changes of states of matter using cornell notes, task cards, and a vocab maps

18. 1. Changes of States of matter
2. Changes between solids and liquids
3. To change from a solid to a liquid, thermal energy is increased.
3. Any change in thermal energy = a change in molecular motion!

19. 3. Melting – what is it?
4. change in state from solid to a liquid
4. Melting point – what is it?
5. melting occurs at a specific temperature
5. melting point of water is 0oC
4. Particles vibrate rapidly and break apart as thermal energy is added

20. 3. Freezing – what is it?
4. change from a liquid to a solid
4. Particles move so slowly that they begin to take on a fixed position due to losing thermal energy
3. Both freezing and melting are physical changes

21. 2. Changes between a liquid and a gas
3. Vaporization – what is it?
4. Change from liquid to a gas
4. Occurs when particles in a liquid gain enough thermal energy to move independently

22. 4. Two types
5.Evaporation – what is it?
6. only takes place on the surface
5. Boiling – what is it?
6. when a liquid changes to a gas below and at the surface
6. boiling point – what is it? Temperature at which a liquid boils.
7. Depends on air pressure

23. 3. Condensation – what is it?
4. change in state from a gas to a liquid
4. Gas particles lose thermal energy
4. Examples
5. Clouds
5. Breathing on a mirror

24. 2. Changes between Solid and Gas
3. Sublimation – what is it?
4. Solids gain enough energy to change into a gas
4. Example
5. Snow not reaching the ground
3. Particles do not pass through a liquid state

25. HW
NTG pages 51-53
