Matter Notes
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
You usually need more than one of the above
characteristics to be considered a chemical change!
• Examples
combining sulfuric acid and sugar
burning a piece of wood
soured milk

Mass vs. Weight
Mass
•
•
Weight
a measure of how much
matter an object is made of
does not change, regardless
of where something or
•
•
someone is
Mass = 59 kg
Weight = 579 N
Why do you
think the
person’s
weight is
less on the
moon?
the force of gravity on an
object
equal to the mass of the
body times the local
acceleration of gravity
Mass = 59 kg
Weight = 96 N

5 Physical States of Matter
• Bose-Einstein
(Newest State)
• Solid
• Liquid
• Gas
• Plasma
Bose-Einstein Condensate
• Exist at extremely
cold temperatures
(around absolute zero
or -460 oF)
• Particles are super
unexcited
• Particles lock or
“clump” together so
firmly that they move
as a single unit
• Definite shape and
volume (?)
Solid
• Particles are
tightly compact
• Particles vibrate
without the ability
to move freely
• Definite shape and
volume
• Solid Animation
Liquid
• Particles are
tightly compact,
but able to move
around close to
each other
• No definite shape,
but definite
volume
• Liquid Animation
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
Plasma
•
•
•
•
•
•
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
Why do you think this is the
most common form/state of
matter in the universe?
Energy and the States of Matter
• The physical states of matter result from the
amount of energy the particles composing the
matter have. Basically, more energy means more
movement for the particles and less energy means
less movement.
• Energy/Temperature and Matter Simulations
– PhET
– BEC: Temperature and Absolute Zero
If you were to compare an ice cube and the steam created
from boiling water, which would you think has more energy?
States of Matter Continuum
What about this continuum could
be considered a little misleading?

Mixture Notes
Density
• a measure of the amount of matter present in a
given volume of a substance
• typically expressed in the following units:
– grams per cubic centimeter (g/cm3) for solids
– grams per milliliter (g/ml) for liquids
• does not depend on how much of a substance you
have (intrinsic property) – in other words, the
density of a gold bar would be the same as the
density of a gold flake
• can change as temperature and pressure change
Which do you think
is more dense? Why?
Layering Liquids
Using a test-tube and the eyedroppers, try to layer the four different
colored liquids so that the colors don’t mix and show distinct layers.
1. Hold the test-tube in your hand at a 45 degree angle.
2. Using the eyedropper from one of the colors, slowly place the
liquid into the test-tube.
3. Repeat step two using the other three liquids until you get them
layered. Record the order of the colors.
If you don’t get clear separation of the colors, you should empty the
contents of the test tube down the drain and start again. These steps
may need to be repeated several times until you discover the correct
order of the colors.
*Placing white paper behind the straws will help you
see the divisions
Layering Liquids - Discussion
1.
Were you capable of layering the four liquids?
If so, what was the correct order from the
bottom up?
2. What difficulties did you experience when
performing this activity?
3. Why do you think the liquids created layers
when putting them in the test tube in the
correct order?
4. Because these liquids are miscible, or partially
miscible, they did not really create distinct
layers. What do you think it means to be
miscible?

Calculating Density
• Density can be calculated by dividing
the mass of an object by its volume
D=m
V
Sample Problem
Timothy found a solid metal block
that has a mass of 100 grams and
a volume of 25 cm3. What would be
the density of the block?
grams = 4 grams
D = 100
25 cm3

27 g and a volume of 7 cm3.

Mixture Notes
Solvent - Solute - Solution
Solvent
Part of the solution that is
present in largest amount
and dissolves a solute
What liquid is called the “universal solvent”? WATER
Solute
Part of solution present in lesser
amount and dissolved by solvent
Solution
A well mixed mixture containing a solvent and at
least one solute that has the same properties
throughout.
Properties of Matter –
Physical Property
Characteristic of a pure substance that can be
observed WITHOUT changing it into another
substance.
Chemical Property
A characteristic of a pure substance that
describes its ability to change into a
DIFFERENT substance.
Mixture
Made of two or more substances- elements,
compounds or both- that are together in the
same place but are not chemically combined.
Heterogeneous Mixture
You can see the different parts
Homogeneous Mixture
So evenly mixed that you can’t see the different
parts
