LIGHT
HEAT
ENERGY

8. 8. Define and give examples of the chemical properties of matter.
Chemical properties – the ability of a substance to undergo a change that transforms it into another substance Examples - Reactivity Decomposition pH Combustibility Toxicity

9. 9. Define and give examples of the physical properties of matter.
Physical property –
A characteristic that can be observed without changing the identity of the substance
Examples :
Solubility
Viscosity
Texture
density

10. 10. Boiling point of a substance can be increased by increasing _____________________.
PRESSURE

11. 11. Explain the differences between intensive and extensive physical properties. List examples of both.
INTENSIVE properties – do Not depend on amount of matter
Examples: Density , conductivity, color
EXTENSIVE properties – do depend on amount of matter
Examples: mass , volume

12. 12. Classify the following as extensive or intensive properties:
conductivity
silver
metallic
density
mass
melting point
Intensive
Extensive

13. 13. Which state of matter is most resistant to compression?
Solid

14. 14. What are mixtures?
A physical combination of two or more substances, each of which retains its own properties

15. 15. List the types of mixtures and give a definition of each.
Homogeneous mixture- a physical combination of substances that has uniform composition throughout
Example: salt water
Heterogeneous mixture- a physical combination of substances that does not have a uniform composition
Example: raisin bran

16. 16. Salt water is what type of mixture?
Homogeneous mixture

17. 17. Evaporation, distillation, filtration, and chromatography are all techniques for separating what?
A mixture

18. 18. What physical property would help you separate a mixture of isopropyl alcohol and water?
Boiling point

19. 19. Density is what type of physical property (intensive/extensive)?

20. 20. Density (does / does not ) depend on amount of substance.

21. 21. What is the formula for density?
Density = mass / volume
D = m v
