discussion on the side.

2
DRQ 1 What is matter?
• Anything that takes up space
• Can be a solid, liquid, gas or plasma

3
8.1 Notes
• Matter and Temperature

4
Day 1-2 Feb 10-11
• DRQ 2 What are 2 similarities and 2
differences between solids and gases?
• Activities
• DRQ\Review DRQ (hand in triangle diagram)
• Create a foldable one page per state of matter.

5
DRQ 2 What are 2 similarities and 2
differences between solids and gases?
• Similarities
• All matter is made of atoms and molecules
• All matter takes up space, and has mass
• All matter has internal energy, kinetic energy
• All matter has movement within the particles

6
Solids
• Unique qualities of solids
• Definite shape
• Definite volume
• Geometric Patterns
• Difficult to change volume
• Sticks together
• Molecules in solids only vibrate
• The kinetic energy is low -movement is confined
to just vibrating in place or rotation
• The force attracting the molecules together is
stronger than the forces pulling the molecules
apart
• That means the molecule become fixed in place
(often line up in a crystalline arrangement.)
• - School for Champions

7
Liquids
• Unique Qualities of Liquids
• Takes the shape of its container
• Cant be squeezed into a smaller volume
• Flows, has more motion
• More kinetic energy than a solid
• sticks together
• Molecules in liquids loosen structure
• Have enough kinetic energy to break out of the
constraints of a structure.
• The force between molecules is only strong enough
to hold the material together in the form of a
liquid.
• School for Champions

8
Gases
• Unique Qualities of Gases
• Springy
• They can change shape
• They can change volume
• Particles are free to move in all directions
• More kinetic energy than a solid or a liquid
• Can completely separate from one another
diffusion
• DOES NOT stick together.
• Molecules in gases run free
• More energetic and are moving rapidly.
• Their kinetic energy is greater than the
attractive force between them.
• A gas will easily spread and not stay in an open
container.
• School for champions

9
Plasma
• Unique Qualities
• Most common form matter
• Found in stars
• Mixture of positively and negatively charged
particles
• As the particles are heated they break into
smaller particles, which are charged
• plasma is a partially ionized gas,
• some electrons are free rather than being bound
to an atom or molecule.
• Plasma is electrically conductive Plasma
typically takes the form of neutral gas-like
clouds, as seen, for example, in the case of
stars.
• in the influence of a magnetic field, it may form
structures such as filaments
• wikipedia

10
Thermal Expansion
• Kinetic theory of matter explains why matter
changes when it is hot or cold
• Almost all matter expands when it gets hot, and
contracts when it gets cold

11
Day 3 Feb 12
• DRQ 3 What is plasma? Where is it found?
• Activities
• DRQ\Review DRQ (Hand in booklet)
• Changes in state info
• Changes in State 8.3 (pages 224-227)

12
DRQ 3 What is plasma? Where is it found?
• Plasma is a lot like a gas, but the atoms are
different because they are made up of free
electrons and ions (unstable, charged atoms) of
the element.
• Northern Lights and ball lightning are types of
plasmas.
• Fluorescent light bulb.
• Inside the long tube is a gas. Electricity flows
through the tube when the light is turned on. The
electricity charges up the gas. This creates
glowing plasma inside the bulb.
• Stars are big balls of gases at really high
temperatures.
• The high temperatures create plasma.
• Fluorescent lights are cold compared to really
hot stars. They are still both forms of plasma,
even with different physical characteristics.

13
Changes in States of Matter
• State describes a physical form of matter. The
key word to notice is physical.
• Things only move from one state to another by
physical changes these are NOT changes in
chemistry!!!

14
Kinetic theory revisited
• You are creating a physical change
• (like increasing the temperature or increasing
pressure)
• If energy is taken away
• (like freezing something or decreasing pressure)

15
Physical changes in state
• One compound or element can move from phase to
phase, but still be the same substance.
• You can see water vapor over a boiling pot of
water. That vapor (or gas) can condense and
become a drop of water.
• If you put that drop in the freezer, it would
become a solid.
• No matter what phase it was in, it was always
water.

16
Example of a chemical change
• Crushing chalk chemical or physical change?
• Physical its still chalk, just looks different
• Adding vinegar chemical or physical change?
• Chemical the acidic vinegar dissolved the chalk
creating a new compund.

17
• Take notes (on the back of tomorrows concept
mapping activity).
• Definition and example of each
• Melting
• Freezing
• Boiling
• Vaporization
• Evaporation

26
DRQ 6 Why does a closed, empty 2-L plastic
bottle cave in when placed in a freezer?
• According to the kinetic theory of matter, the
particles of the gas will loose energy and slow
down their movement.
• The gas particles will not collide with each
other as much, and will not require as much
space.
• The volume of the gas will shrink, and because
the pressure of the air outside, the bottle will
collapse on itself.

Charles vs. Boyle
• A significant advance in the study of gases came
in the early 1800's in France.
• Hot air balloons were extremely popular at that
time and scientists were eager to improve the
performance of their balloons.
• Two of the prominent French scientists, Jacques
detailed measurements on how the volume of a gas
was affected by the temperature of the gas.
• Boyle's Law is named after the Irish natural
philosopher Robert Boyle (1627-1691) who was the
first to publish it in 1662.
• The relationship between pressure and volume was
brought to the attention of Boyle by two friends
and amateur scientists, who discovered it.
• Boyle confirmed their discovery through
experiments and published the results.

Uses of Fluids

39
DRQ 10 Why is gas under more pressure when you
make its container smaller?
• Boyles Law states that when you make the space
smaller, the gas will increase in pressure.
• This is because pressure is a measure of the
force on an area.
• The force is created by the collisions of the gas
molecules.
• When the space is smaller, the molecules will
collide with each other more, and the amount of
force will increase.
• When the space is larger, the molecules will
collide less, and the amount of force will
decrease.

Day 1 Feb 27
• DRQ 11 What does it mean to displace a fluid?
• Activities
• DRQ\Review DRQ (check for homework completion)
• Buoyancy demos
• Buoyancy video
• Homework none

50
DRQ 11 What does it mean to displace water?
• Displacement occurs when an object is put in a
fluid, pushing it out of the way and taking its
place. ...
• Balloons in the back which is displacing more
water?

51
Demo of Displacement
• Heres a clip that will show you how to measure
an objects displacement.

52
Buoyancy
• Objects like boats float, even if the metal that
makes up their hull is heavier and denser than
water, because of a force called buoyancy. That
means the water pushes up against them.
• Buoyant force is the force of a fluid on an
object.
• As long as the buoyant force is more than the
objects weight, the object will float.

53
You sinking or floating
• A boat is built to spread out the metal over a
wide area
• it floats because the water pushes up on a lot
of the metal in fact, it pushes the same as the
boats weight.
• Think about the last time you went swimming.
curled up into a ball, did you sink?
• When you stretched out flat, did you float?

54
Sink vs. float
• Thats because more water pushes against you
since your body is laid out flatter. When you
curl up into a ball, less water is pushing
against you.
• Its the same concept as the bed of nails since
there is less pressure on any one point. If you
curl up, it will hurt, youll put too much
pressure on one area.

55
Two Pieces of Clay
• Both weigh the same.
• One displaces more water because of its shape
it will float.
• The other sinks.

56
Hot air balloon
• A hot air balloon has warm gases inside it.
• Those warm gases displace some of the air in the
room, or the atmosphere.
• Since the gases the balloon displaces weighs more
than the balloon and the warm gases in it, the
balloon will float on the air.

57
Buoyancy
• Heres a video for you!

DRQ 12 What is buoyant force?
• Buoyant force is the upward force that a fluid
puts on an object.
• When the buoyant force on an object is greater
than its weight, it will float.

60

65
Solids vs. Liquids vs. Gas vs. Plasma Solid to a gas sublimation, vibrate, geometric patterns, melt Liquids more NRG than solid, takes shape of container, flow, vol. doesnt change Gases more NRG than liq. Less than plasma, vol changes, particles separate Plasma /- charges, lots NRG, particles separate
Thermal expansion When something is heated it expands, when something cools it contracts, because the heat is really NRG and it makes the particles move faster and they need more space. Thermometer, concrete bridge expansion joints
The Kinetic Theory Tiny particles in constant motion makes up all matter, in a solid it lacks energy to move out of position, a liquid has enough energy to move, but not out of position, a gas and a plasma has enough energy to move completely away from other particles
Pressure Pressure is the amount of force exerted on an area, unit is Pascal. All matter moves from areas of high to low pressure. Faster moving air has lower pressure.
Boyles and Charles laws Charles Celsius, changes in temperature create changes in gas volume. When volume goes up, pressure goes up. Boyle Bumps, changes in the size of the container affect pressure, squeezing increases pressure.
Archimedes, Bernoullis and Pascals principle Archimedes buoyant force on an object is equal to the weight of the matter displaced by the object boats/hot air balloons Pascal pressure flows throughout a liquid without changing toothpaste, hydraulics Bernoulli's faster fluid has less pressure, how planes fly/sailboats
66
Chapter Review

(a).
• Particles separate completely from each other in
a gas (a).
• The state of the matter in the sun and other
stars is primarily plasma (b).
• In general, as a solid is heated, it expands (d).
• A materials heat of fusion give the amount of
energy needed to melt a solid (c.

68
Chapter Review
1. The hot tea transfers energy to particles in the
glass and the ice. The tea loses energy so it
cools. The glass and the ice take energy from the
tea. The glass warms up and the ice melts as the
2. Water vapor in the air is cooled by the glass.
The particles of vapor lose energy and condense
on the glass.
3. The deeper water contacts more of the surface
area of your body. It resists gravity and the
upward buoyant force of the water acts against
the downward force (gravity) of your weight on
the rocks.
4. According to Charless law, as the temperature of
a gas changes, so does the volume. As the volume
changes, so does the pressure, according to
Boyles law. (FYI you should not check or
change air pressure on a hot tire)
