1. MATTER & ITS PROPERTIES NOTESHEET

2. 1. MATTER: O Matter is anything that has mass and takes up space.

3. 2. PROPERTIES: O Qualities or traits belonging to an individual or thing. LET’S DISCOVER PROPERTIES OF MATTER: http://studyjams.scholastic.com/studyjams/ja ms/science/matter/properties-of-matter.htm

4. 3. PHYSICAL PROPERTIES: O. Physical properties are any properties of matter which can be observed without changing the chemical identity.

5. 4. EXAMPLES OF PHYSICAL PROPERTIES INCLUDE: O 1. The color of a shirt O 2. The weight of a bowling ball O 3. The length of a football field.

6. 5. CHEMICAL PROPERTIES: O Any characteristic that gives a substance the ability to undergo a change that results in a new substance

7. 6. EXAMPLES OF CHEMICAL PROPERTIES: O A. Toxicity O B. Oxidation O C. Flammability

8. 7. CHEMICAL OR PHYSICAL? O A. CHEMICAL O B. PHYSICAL O C. PHYSICAL O E. PHYSICAL O F. PHYSICAL O D. CHEMICAL O G. CHEMICAL O H. CHEMICAL

10. 8. STATES OF MATTER: O THE 3 MAIN STATES OF MATTER ARE: SOLID, LIQUID AND GAS. O Let’s have a look at the differing states of matter: http://studyjams.scholastic.com/studyjam s/jams/science/matter/solids-liquids- gases.htm

11. 9. WHICH STATE OF MATTER: O A. GAS O B. SOLID O C. LIQUID

12. 10. Name 3 things that are solids: O EXAMPLES: wood, car, concrete, brick, chair and table

13. 11. Name 3 things that are liquids: O EXAMPLES: water, milk, orange juice, gasoline and soda

14. 12. Name 3 things that are gases: O EXAMPLES: Helium, water vapor, oxygen, nitrogen and carbon dioxide

15. 13. Density: O A physical property of matter. The mass per unit volume of a substance at a particular temperature and pressure. O USE THIS FORMULA TO FIND DENSITY: O D=m/v

16. 14. What is the 4 th phase of matter? O PLASMA

17. 15. Examples of Plasma: O Lightning, solar wind, stars and the tail of a comet

18. 16. Physical Changes O Any characteristic of a material that can be observed or measured without changing the identity of the material

19. 17. Examples of Physical Changes 1. Bending a piece of plastic that snaps back into shape. 2. A chocolate bar melts. 3. A tree is cut up to be used as firewood. 4. A t-shirt shrinks in the dryer. 5. You gained ten pounds.

20. 18. Chemical Change: O A change in the identity of a substance due to the chemical properties in that substance.

21. 19. Examples of a chemical change: O Eating a sandwich O Rust on metal O Wood burning

22. PHYSICAL VS. CHEMICAL CHANGES VIDEO: O http://www.learn360.com/ShowVideo.aspx? lid=6818736&SearchText=chemical+and+p hysical+change&ID=138912 http://www.learn360.com/ShowVideo.aspx? lid=6818736&SearchText=chemical+and+p hysical+change&ID=138912

23. 20. Six Phases of Matter O Condensation, evaporation, sublimation, deposition, freezing, and melting

24. 21. Condensation O is the conversion of a vapor or gas to a liquid. O Example: Water molecules in the air as a vapor hit the colder surface of the can and turn into liquid water

25. 22. Evaporation O is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure. O Evaporation is a fundamental part of the water cycle and is constantly occurring throughout nature.

26. 23. Sublimation O is a chemical process where a solid turns into a gas without going through a liquid stage. O Example: When ice cubes shrink in the freezer.

27. 24. Deposition O is a process where a gas changes phase and turns directly in solid without passing through the liquid phase. O Example: Snow that forms in clouds. The water vapor changes directly to ice without first becoming a liquid.

28. 25. Melting point O is the temperature at which a solid and liquid phase may coexist in equilibrium (the same amount).

29. 26. Freezing point O is almost always an exothermic process, meaning that as liquid changes into solid, where heat and pressure is released.
