1. Physical Property
Characteristic of a pure substance that can be observed WITHOUT changing it into another substance.

2. Physical Properties of Matter
It does NOT CHANGE into something else
Examples
color
shape
taste
state/phase
density
D = m V

3. Physical Change a change in shape, size, color, or state
a change without a change in chemical composition
a change that is reversible
The Mixtures Lab
Examples
tearing paper
cutting your hair
change in state

4. Page 29
Chemical Property
A characteristic of a pure substance that describes its ability to change into a DIFFERENT substance.

5. Chemical Properties of Matter
changes into a new substance
Examples
flammability
reactivity with vinegar
reactivity with oxygen
Iron + Oxygen  Iron oxide (rust)
2Fe + 3O2  Fe2O3

6. combining sulfuric acid and sugar
Chemical Change
a change in which a substance becomes another substance having different properties
a change that is not reversible using ordinary physical means
Changes that usually cause heat, sound, light, odor, fizzing/foaming, color changes
Examples
combining sulfuric acid and sugar
burning a piece of wood
soured milk
Salt:

7. Chemical or Physical Property?
Paper is white
Boiling point of H2O is 100oC
Zinc reacts with hydrochloric acid and creates hydrogen gas
Nitrogen does not burn
Sulfur smells like rotten eggs

8. I.S. Learning Goal:
I can describe predict properties of elements and compounds using trends of the periodic table (e.g., metals, non-metals, bonding – ionic/covalent).

12. 4 Physical States of Matter
Solid
Liquid
Gas
Plasma

13. Solid Particles are tightly compact
Particles vibrate without the ability to move freely
Definite shape and volume
Solid Animation

14. Liquid
Particles are tightly compact, but able to move around close to each other
No definite shape, but definite volume
Liquid Animation

15. Gas Particles can easily spread out or move close together
Particle move freely and with a lot of energy
No definite shape or volume
Gas Simulation

16. Plasma
Why do you think this is the most common form/state of matter in the universe?
Exist at extremely high temperatures (several million degrees Celsius)
Particles are broken apart
Particles move freely and with extremely high energy
This form is not too common on Earth, however it is the most common form of matter in the universe
No definite shape or volume (?)
Examples: Florescent and neon lights, lightning, aurora borealis - + + + - -
