 Assignment
• Turn in
3
players
 Try
to collect all the cards which describe a
state
 Each player pick one card
 One by one (clockwise, starting with
youngest player) pick a card
• If the card matches your state, keep it. If not, put it
back
• Winner: First player to get all 10 cards for one state
 Place
your 10 cards into two categories
• Category 1: Describes what we find by
observing
• Category 2: Describes how the “Particle Theory”
explains observations
 Write
a paragraph about your state
• Use the cards to help you
 If
you haven’t finished that worksheet
• Finish it NOW!!!!!!
• Turn it in before you leave

question and answers
 Temperature
is a measure of…
• A. heat
• B. how hot something is
• C. How cold something is
• D. average kinetic energy
 Solids, Liquids
• Card game
and Gases Practice
2
players
 Place cards face down in a pile
 One
by one (starting with oldest player)
choose a card and put it on the board.
 Goal: Get
Four in a row. It can be vertical,
horizontal, or diagonal
 The
Kinetic Molecular Theory explains
the forces between molecules and the
energy that they possess.
• This theory has 3 basic assumptions.
 Matter is composed of small particles (molecules).
 The measure of space that the molecules occupy (volume) is
derived from the space in between the molecules and not
the space the molecules contain themselves.
 The molecules are in constant motion
 This
motion is different for the 3 states of
matter.
• Solid - Molecules are held close to each other by
their attractions of charge. They will bend and/or
vibrate, but will stay in close proximity.
• Liquid - Molecules will flow or glide over one
another, but stay toward the bottom of the container.
Motion is a bit more random than that of a solid.
• Gas - Molecules are in continual straight line motion.
The kinetic energy of the molecule is greater than
the attractive force between them, thus they are
much farther apart and move freely of each other. •
 When the molecules collide with each other, or with the
walls of a container, there is no loss of energy.

Introduction
next Wednesday
• Plenty of time
• Limited time in class to work on it
• We will continue learning
• Any questions?
• What are your partners?
• What compound?
 Volatile
liquids‐ liquids that evaporate
readily
 Nonvolatile liquids‐ evaporate slowly,
have strong attractive forces between
particles
 Phase
diagrams‐ a graph of pressure
versus temperature that shows the
conditions under which the phases of a
substance exist
 Triple point‐ indicates the temperature
and pressure conditions at which the
solid, liquid, and vapor of the substance
can coexist at equilibrium
•
Critical temperature‐ the temperature
above which the substance cannot exist
in the liquid state
• Water 373.99°C

Critical pressure‐ the lowest pressure at
which the substance can exist as a liquid
at the critical temperature
• Water 217.75 atm
 Freezing
Point (Fusion & Crystallization
Point)
• Temperature at which the liquid becomes a
solid

Melting Point
• Temperature at which the solid becomes a
liquid
 Melting Point and Freezing Point are the SAME
Temperature
•
Boiling Point
• Temperature at which the liquid becomes a gas
 Normal Boiling Point is at atmospheric pressure (1
atm or 760 torr or 101.3 kPa)

Condensing Point
• Temperature at which the gas becomes a liquid
 The Boiling and Condensing Point are the SAME
Temperature
 You
should work on your project
• I have given you examples in your notes
• Remember it is due Wednesday
• Not using class time to work on it
