2. Physical &Chemical Properties

3. Physical & Chemical Topics
Physical properties
Chemical properties
Rule of thumb
Matter

4. Physical Property Observable property
Observed without changing the identity of the substance
Substance remains the same
Only appearance changes
Ex. State, color, size, melting point, boiling point, solubility

5. Physical Change Alters a substance without changing its composition.
Physical property changes but substance remains same.
can be “easily” undone
Ex. cut, bend, phase change, solubility,density

6. Examples of Physical Change
Cut
Phase change

7. Physical properties Extensive - depends on the amount of matter.
Arbor Scientific

8. Physical properties
Intensive - does NOT depend on the amount of matter.
Topics
University of Cambridge

9. Chemical Property
Describes how a substance changes into a new substance.
Describes a substance’s ability to change.
Example - flammability (ability to burn)

10. Chemical Change
Changing one substance into a new & different substance.
Process by which substance changes
Starting substance = reactant
Ending substance (new) = product
ex. burning, respiration, digestion, rusting, baking a cake

11. Examples of Chemical Change
Baking bread
Rusting
Respiration
Digestion
Burning

12. Rule of Thumb
If a precipitate, gas, energy change or sometimes color change occurs a chemical change has probably taken place.
Topics
Petrucci, Harwood, & Herring

13. Matter anything with mass and volume
mass – measure of the amount of matter.
volume – how much space it takes up.

14. Matter Anything with mass and volume Examples of matter
Chair
Person
Book
Examples of not matter
Light
Heat

15. Matter
Is air matter?

16. Atom
Smallest unit of an element that maintains the properties of that element.
building block of all matter
fundamental particle

17. Element made of only one kind of atom
simplest form of matter that can exist under normal conditions
cannot be separated into simpler substances under normal conditions
approx 90 naturally occurring (others artificial)

19. Molecule Smallest unit of a compound
Charlene Marsh

Molecule
Smallest unit of a compound
Compound - substance made from the atoms of two or more elements chemically bonded.
Topics
PowerMasters Motorsports Academy

20. Pure Substances elements and compounds made of only one kind of matter
same throughout
same every where
in world
ex. sugar (C12H22O11),
copper (Cu)

21. Classification of Matter

22. Mixtures physical blend of two or more substances variable composition
matter that can be physically separated
ex. air, forest, beef stew, gold jewelry

23. Classification of Matter

24. Heterogeneous Mixture
heterogeneous – not uniform composition
two or more groups
ex. tossed salad, milk straight from the cow

25. Homogenous Mixture uniform composition evenly distributed
ex. salt water, Kool-Aide, gold jewelry.

26. Classification of Matter

27. Colloid mixture between homogeneous and heterogeneous.
particles do not settle
scatters light
appears cloudy.

28. Tyndall Effect

29. Classification of Matter
