 Solid
 Liquid

KINETIC THEORY OF MATTER
•Particles of solids are
tightly packed, vibrating
about a fixed position.
•Solids have a definite
shape and a definite
volume.

slide over one another.

Liquids have an
indefinite shape and a
definite volume.

BUT WHAT HAPPENS IF YOU RAISE
THE TEMPERATURE TO SUPER-HIGH
LEVELS…
BETWEEN
1000°C AND 1,000,000,000°C ?
Will everything
just be a gas?
STATES OF MATTER
PLASMA
A plasma is an
ionized gas.
 A plasma is a very
good conductor of
electricity and is
affected by
magnetic fields.
 Plasmas, like gases
have an indefinite
shape and an
indefinite volume.

• Plasma is a
common state
of matter
STATES OF MATTER
SOLID
Tightly packed,
in a regular
pattern
Vibrate, but do
not move from
place to place
LIQUID
Close together
with no regular
arrangement.
Vibrate, move
about, and slide
past each other
GAS
Well separated
with no regular
arrangement.
Vibrate and
move freely at
high speeds
PLASMA
Has no definite
volume or shape
and is
composed of
electrical
charged
particles
SOME PLACES WHERE PLASMAS ARE
FOUND…
1. Flames
2. Lightning
3. Aurora (Northern Lights)
The Sun is an example of a star in its
plasma state

2 minutes: Record any information you can remember without
notes

2 minutes: Share with one other student. Add his/her knowledge
to your list.

1.) Which state of matter has a
definite shape and has a definite
volume?
2.) Draw a picture of what gas
molecules look like in a beaker.
LAW OF CONSERVATION OF MATTER
The
law of conservation of mass indicates that mass
cannot be created nor destroyed only transformed into
different matter. This means the total mass of reactants in
a chemical reaction will equal the total mass of the
products. If a gas is produced during a reaction, which
mass is often forgotten when calculating the final mass
because we are unable to see the gas.

LAB

Material Managers please come up and grab a lab hand out for
everyone at your group.

Everyone needs to quietly read the directions of the lab if you fail
to follow the lab procedure you will be dismissed from lab and
will be doing book work.

Alternative assignment: Read pgs. 64-78 complete all sections

1.) Which state of matter has an
indefinite shape and has a indefinite
volume?
2.)What is sublimation.
WARM UP
Why is it very dangerous to
leave a child or animal in a
locked car with the window
closed in bright sunlight?
WORK SESSION
Go to pages 74-79 to complete the guided
notes on phase changes.
You can also use your notes to help you.
WORK SESSION
Be
the teacher: present three
key ideas you think everyone
should have learned.
We
learned what? Students
write open ended questions on
a half sheet of paper.
CLOSING
Two
students are selected to come forward,
The first students draws a questions card and
posed the question to the class. After the class
discusses the question and answers with their
partner - the second student draws a student
name card to respond to the questions.
WARM UP
Draw and label the
different parts of the
atom.

THERMAL ENERGY AND HEAT TRANSFER
Take
out your science notebooks and
start to record your notes on the next
available odd page.
THERMAL ENERGY
The
sum of ALL of the energy possessed by
ALL of the particles in a substance
Volume
affects thermal energy (the bigger
the object the more thermal energy it has)
Temperature
affects thermal energy: the
higher the temp, the more thermal energy
ENERGY AND CHANGING STATES OF MATTER
Adding
energy causes particles to increase
in speed, increase their spacing resulting in
higher temp
Removing
energy causes particles to
decrease in speed, decreasing their
spacing resulting in lower temp
Boiling
and condensation points are the
same temp…(100°C/ 212°F for H2O)
ENERGY AND CHANGING STATES OF MATTER
Melting
& freezing points are the same
temp…0°C/ 32°F (H2O)
Sublimation
occurs when the surface
of a solid gains enough thermal energy
to become a gas, skipping the liquid
phase
TEMPERATURE AND HEAT
Temperature
is the AVERAGE kinetic energy (
energy of motion) of the particle sin a substances
Temp
is not affected by volume (a giant piece of
ice will have the same temp as a small piece of ice)
Change
in thermal energy does not affect
temperature
TEMPERATURE AND HEAT
Heat
is the transfer or flow of thermal energy
From
higher temp to lower temp
Heat
is transferred 3 ways
Conduction
is by direct particle contact.
Particle collisions
TEMPERATURE AND HEAT
Convection
results from unequal heating in a liquid
or a gas, where the warmer substance is less dense
b/c its particles are further apart. They rise as the
cooler substance is denser b/c its particles are closer
together, which causes them to sink.
TEMPERATURE AND HEAT
Radiation requires no medium (that’s why the
Sun’s heat energy can travel through the
empty space/vacuum of outer space). There
are no collisions between particles. The energy
excites the particles of the substance it strikes
TWO MINUTE TALK
 Procedure:
 1.
Group students into pairs.
 2.
Inform students that they will each be talking about topic X for two
minutes. They will need to select which student will begin first. An easy way
to do this is to say something like: "Find out whose birthday comes first in a
calendar year." Then tell students that, "That person gets to go second!"
 3.
Using a stop watch or other timing device, tell students to begin talking.
 4.
At two minutes, instruct students to switch. At this point, the other partner
begins talking. It is okay for the second person to repeat some of the things
the first person said. However, they are encouraged to try and think of new
information to share.
 5.
Have a few groups share some of their responses with the entire class
when the activity is done.
