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).
