5. Physical properties Without any change in composition. Can be classified as intensive and extensive.

6. Physical Properties of matter Intensive Properties Extensive Properties

7. Intensive properties It does not depend on the amount of matter that is present.

8. extensive properties It depend on the amount of matter that is present.

9. Intensive vs. extensive INTENSIVE EXTENSIVE Color Mass Taste Volume Melting Point Length Boiling Point Shape Density Luster Hardness

10. example Two Beakers A and B are filled with water. Question: What is the volume of A and B? Is the volume different? A is 250 mL; B is 750 mL. Yes, the volumes are different.

11. Example: VOLUME is an extensive property. It depends on the amount.

12. Example: What about DENSITY? A.) 1.0 g/mL Water has always a density of 1.0 g/ mL.

13. Example: COLOR is an intensive property. It does not depend on the amount.

14. Mass density and VOLUME

15. MASS The measure of how much matter is in an object. Usually in grams (g), kilograms (kg), or pounds ( lbs ).

16. volume The amount of space that a substance occupies. Usually in mL, liter (L), or ounce ( oz ).

17. density The amount of mass in a specified space. ( D = ) Usually in g/mL, g/ or kg/ .  

18. F ormulas for mass, density and volume.

19. VOLUME COMMON FORMULAS

20. Boiling point A temperature at which a liquid changes to gas (evaporation).

21. melting point A temperature at which a solid changes to liquid (melting).

22. malleability Capability of metal to be hammered into thin shits.

23. conductivity Ability to conduct heat and electricity.

24. Magnet property Ability to attract materials made of iron and steel.

25. ductility Ability to be drawn into wires.

26. chemical properties Change in composition or formula.

27. Some chemical properties have the following characteristics. Ability to CHANGE IN COLOR. Ability to CHANGE IN ODOR. Ability to FORM GASES. Ability to GIVE OFF LIGHT and HEAT. Ability to FORM PRECIPITATE. Ability to CHANGE IN TEMPERATURE OR ENERGY . Ability to CHANGE IN FORM.

28. TAKE NOTE: ALL CHEMICAL REACTIONS ARE CHEMICAL CHANGE.

29. EXAMPLES: PHYSICAL CHANGES CHEMICAL CHANGES Clay is molded into a new shape. Milks goes sour. Butter melts on warm toast. Jewelry tarnishes. A juice bow in the freezer, freezes. Gasoline ignited. Rubbing alcohol evaporates in your hand. You fry an egg.
