1 kg = 9.8 N

3. I. General Properties of Matter
anything that has mass and volume
-General properties of matter include mass, weight, volume, and density.

4. A. Mass *amount of matter in an object(constant)
*measure of the inertia of an object.
*Inertia:
resistance to change in motion.

5. B. Weight *response of mass to the pull of gravity(not constant)
force of attraction between objects.
-Metric unit of weight is the Newton(N).
Ex:

6. C. Volume
*amount of space an object takes up.

7. D. Density -Ex: p48 -Density of water is 1g/ml.
*Specific gravity: ratio of the mass of a substance to the mass of an equal volume of water.

8. II. Phases of Matter
*Physical properties: can be observed without changing the identity of the substance.
Ex’s:
-Four phases of matter:
solid, liquid, gas, and plasma.
p70-73

9. A. Solid -definite shape and definite volume. *Crystal:
particles arranged in a regular, repeating pattern.
*Crystalline solids:
made up of crystals.
*Amorphous solids:
lose their shape under certain conditions.

10. B. Liquids -take the shape of their container.
-No definite shape, but definite volume.
#4(Breathtaking! Slow Motion Puff)
*Viscosity:
resistance of liquid to flow.

11. C. Gases pp88 -no definite shape, or definite volume.
*Boyle’s Law: vol decreases, pressure increases.
-P1 V1 = P2 V2
-varies inversely
-graph ex:

12. *Charles’s Law: temp increases, vol increases.
- T1 V2 = T2 V1
-varies directly
-graph ex:

13. Boyle’s and Charles Law: Examples

14. D. Plasma -Stars have matter in the plasma phase.
-very high in energy.

15. III. Phase Change -Phase change by adding or taking away nrg.
-Phase changes in matter:
1. melting
2. freezing
3. vaporization
4. condensation
5. Sublimation
6. Deposition
*Physical Change: change in phase
ex: pp74-77

16. A. solid - liquid *Melting: *Melting point: *Freezing:
*Freezing point:

17. B. liquid - gas *Vaporization: liquid to a gas *Evaporation: *Boiling:
*Boiling Point:
*Condensation:
gas to liquids

18. C. solid - gas *Sublimation: solid to gas ex: dry ice *Deposition:
gas to solid
ex: frost

19. D. heat, temp, and phase chng
-Phase changes are accompanied by increases in heat nrg but not by increases in temp.

21. IV. Chemical Properties and Changes
*Chemical properties: substance changes into other new substances.
1. Flammability
2. Ability to support burning

22. -Chem property describes a substance’s ability to change into a diff subst.
-Chem chng :
process by which the substance chngs.
*Chem Rxn: chem. Chng
-produces new subst with new and diff phys and chem. properties.
