1. Matter & Change
Chemistry
J.P. Hancock

2. EQ: How can properties used to describe matter be classified?
List as many properties that you can of a can of coke fresh out of the vending machine.

3. EQ: How can properties used to describe matter be classified?
Extensive Properties- depends on the amount of matter in a sample
Changes when the size of the sample changes.
Mass
Volume
Length
Total charge

4. EQ: How can properties used to describe matter be classified?
Intensive Properties-depends on the type of matter in the sample, not the amount
Doesn’t change when you take away some of the sample
Temperature
Refractive Index
Density
Hardness of an object

5. Matter Matter Mass Anything that has mass and takes up space
The amount of substance in an object

6. Substance Substance Uniform and definite composition
Identical intensive properties

7. Physical Properties
Quality or condition that can be observed or measured without changing the substances composition
Used to identify substances

8. 4 States of Matter
SOLID
LIQUID
GAS
PLASMA

10.                                
MOLECULAR LOOK
solid
liquid
gas

11. SOLID DEFINITE SHAPE & VOLUME PARTICLES TIGHTLY PACKED
LOW KINETIC ENERGY(PARTICLES CAN VIBRATE AROUND EACH OTHER
STRONG INTERMOLECULAR FORCES(PARTICLES DO NOT HAVE ENOUGH ENERGY TO CHANGE THEIR POSITION

12. TYPES OF SOLIDS AMORPHOUS CRYSTALLINE
Particles that do not have a crystalline form
No definite melting point
(will get softer and softer before liquid)
Examples
Glass
Rubber
Plastic
Chocolate
Wax
CRYSTALLINE
Particles arranged in regular geometric patterns
Have a definite melting point
Examples
Salt
Sugar
sand

13. Glass Blowing Video
What type of solid is glass?
While

15. LIQUID DEFINITE VOLUME PARTICLES PACKED TIGHT MORE KINETIC ENERGY
WEAKER INTERMOLECULAR FORCES
PARTICLES CAN MOVE OVER AND AROUND EACH OTHER-allowing the liquid to take the shape of the container

16. GAS NO DEFINITE SHAPE NOR VOLUME PARTICLES SPREAD APART
GREATEST KINETIC ENERGY
WEAKEST INTERMOLECULAR FORCES
PARTICLES HAVE ENOUGH ENERGY TO SEPARATE FROM ONE ANOTHER
PARTICLES CAN BE COMPRESSED

17. Gas Vapor Used to describe substances that are (g) at room temp.
Used to describe substances that are generally (l) or (s) at room temp.

18. PLASMA An ionized gas OR charged gas. (+ and – charged electrons)
Some of the electrons break free from, but travel with, their nucleus
Most common state of matter in the universe.
Much of the mass of the universe is plasma
Examples
-Lightning -Fluorescent Light Bulbs
-Sun -Plasma Display Panels(TV)
-Stars Aurora Borealis (interaction of earth’s
-Neon “Lights” magnetic field and a plasma)

19. PLASMA

20. Plasma Ball Observations
What do you observe about the ball itself?
What happens when the following tubes of gas are brought close to the ball?
Krypton Gas
Neon
Helium
Mercury
Hydrogen
Nitrogen
Fluorescent light bulb

21. Examples of Physical Properties

22. Examples of Physical Properties

23. Physical Changes
Changes in the form or appearance w/o making the substance a new substance.
Ex chop wood, bend wire, melt ice
All changes in the states of matter

24. 2 Categories of Physical Changes
Reversible
Examples
Irreversible

25. Questioning and Thinking
Create 1 level one question
Create 2 level two questions
Create 2 level three questions
Why do all samples of a substance have the same intensive properties?
