1 Physical and Chemical Properties of Matter
Objective: Students will classify matter by physical and chemical properties and identify changes in matter.

2 Matter is EVERYWHERE and is found in different forms as solids, liquids and gases.

3 When we examine a substance, we are interested in its properties
When we examine a substance, we are interested in its properties. A property is something about a substance that can help to define it. Properties can be both physical and chemical.

4 Properties of matter are both
PHYSICAL and CHEMICAL

5 PHYSICAL PROPERTIES Physical properties are thing about matter that can be observed without changing the substance into a different substance. There are many different physical properties that can be observed. H2O

6 Examples of Physical Properties
Color – Gold Au GOLD Density g/cm3

7 PHYSICAL PROPERTIES: GOLD Metal- STATE (solid, liquid or gas)

8 GOLD PHYSICAL PROPERTIES: Boiling point- 2807 ° F
Melting point- 1947° F GOLD

9 GOLD PHYSICAL PROPERTIES: Malleable- Bendable-forms into thin sheet
Conductivity- Conducts heat and electricity Ductile- stretched into wire

10 PHYSICAL PROPERTIES: Soluble: to dissolve (without fizzing or bubbling!)

11 Examples of Physical Changes
Size change Shape change

12 Examples of Physical Changes
State change Solid liquid gas

13 When a physical change occurs, the chemical composition of that substance DOES NOT CHANGE?
THE MATTER basically STAYS THE SAME Au Au Au

14 Iron + Oxygen = Rust 4Fe + 3O2 = 2Fe2O3 CHEMICAL PROPERTIES
Chemical properties are characteristics of a substance that are observed when it REACTS or changes to produce different substances. Iron Oxygen = Rust 4Fe O = 2Fe2O3

15 Examples of Chemical Properties Reaction to……..
WATER OXYGEN CHEMICALS

16 REACTION TO…….. LIGHT

17 REACTION TO …… Heat Flammability

18 Iron + Oxygen = Rust 4Fe + 3O2 = 2Fe2O3
When matter undergoes a CHEMICAL CHANGE the atoms in the original substance are rearranged and produce new substances that are structurally different than the original matter. Iron Oxygen = Rust 4Fe O = 2Fe2O3

19 FIZZING and BUBBLING Signs that matter is undergoing
a chemical change: Giving off HEAT/SMOKE FIZZING and BUBBLING

20 Color CHANGE

21 Smell Change

22 When matter undergoes a CHEMICAL CHANGE, the atoms in the original substance are rearranged and produce new substances that are structurally different than the original matter. COPPER

23 ***MATTER FORMS A _________________ SUBSTANCE TOTALLY NEW

24 Review Physical or Chemical Properties of Matter WARM-UP Directions:
*Number your paper from 1 to 10. *For each item, label it as a physical property (P) or a chemical property (C).

25 Physical or Chemical Property?
1. Flammability

26 Physical or Chemical Property?
2. Malleability

27 Physical or Chemical Property?
3. Melting and Boiling Point

28 Physical or Chemical Property?
4. Oxidation (Rusting)

29 Physical or Chemical Property?
5. Conductivity

30 Physical or Chemical Property?
6. Dissolving without temperature change. No bubbling or Fizzing…

31 Physical or Chemical Property?
Dissolving with a temperature change. Fizzing and bubbling….smell release.

32 Chemical or Physical Property?
Oxidation (Tarnishing) No Tarnish Tarnished

33 Physical or Chemical Property?
9. A totally new substance is formed.

34 Physical or Chemical Property?
10. The substance remains the SAME…..

35 Now….Check your answers!

36 1. Flammability Chemical Property

37 2. Malleability Physical Property

38 3. Melting and Boiling Point
