Print off topic outline by Monday.
Test on this unit will be on Friday, Feb. 10
You will be completing 2-3 labs between now and then…prepare for a fast
unit! 
Textbook Reference: Chapters 10 and 11. You WILL need your textbook
every day for the next 2 weeks. Bring one or share one.
When you think of Heat, Thermal
Energy, and Temperature, what
comes to mind?
3 min: write on your own warm-up
sheet (a new one! It’s 2nd semester!)

The rest of this power point is filled with guiding
questions (and online resource links) to help you
gather information for all the syll. Statements
for this unit
Take good notes (on your own…) related to each
of the questions on the slides.
You will NOT be getting lectures in class for this
unit.
There are, however, the presentations I used
last year posted online—use those as
supplemental notes 
We WILL be doing 2 labs next week.
All syllabus statements must be completed by
the beginning of class on Friday, Feb. 10

Please check WebAssign. There will be
several relatively short homework sets,
related to major topics in this unit.
All will be open until 7:25 AM on Friday, Feb.
10 (the day of the test).
Don’t forget to do any of them!

What are the units of temperature?
Which units of temperature are metric?
Which is the fundamental metric unit?
How do you convert between each of the
temperature units?
 Use the following resources:

What IS absolute zero?
How was it determined?
What is the temperature of Absolute Zero in
the Celsius temperature scale?

What does “Thermometric” mean?
There are several examples of these
properties. List and describe each of them.
 Resource #4
Homework #2: (due to turnitin.com no later than Friday, Feb. 10, 2012)
Design Lab: Design a lab to study the effect of temperature on a
variable related to your choice of thermometric property. (please be
specific about which thermometric property your are studying)
Use the IB “Design” rubric

Resource #7
If you were to construct a thermometer, why
must you have 2 known, standard (fixed)
points with which to work?
Describe HOW you would calibrate (create
the accurate scale) a standard alcohol
thermometer that was originally blank (no
scale on it at all)

Define the following:
 Thermal Energy (internal energy):
 Heat:
 Temperature:
Resource #9
Resource #10
Resource #11
 How is the direction of thermal energy transfer
determined? (3.1.1)
 Sketch and interpret a kinetic energy distribution
for a substance at various temperatures (see last
year’s notes… OR… Resource E Resource F

Define/Describe each of the following:
 Conduction
 Convection
 Radiation
Note: concepts only—you don’t need to do any
calculations for any of these methods of energy
transfer

What is a mole?
How is molar mass of an element
determined? (note: if you don’t have a
periodic table, let Ms. Fowler know…)
How is molecular molar mass determined?
What is Avogadro’s number? Where did it
come from?
Resource #14 Resource #15
What is meant by “Heat Capacity”?
 What variables will affect the heat capacity of
a substance?
 Mathematically, how is heat capacity
determined? With what units?
Resource #16 Resource #17
 How is specific heat capacity “specific”?
 Mathematically, how is specific heat capacity
determined? With what units?
Resource #18 Resource #19 Resource #20

HW reminder! Calorimetry lab (data table and
analysis questions A-F) due on Friday, 2/10/12!
Sample Problems: there is a Word Document on both
websites with practice problems (and answers)—not
required to complete all of them, but 3.2.2 asks you to
complete some problems…I’d recommend 2-3 be put
in your syll. state. Book.
HW reminder: WA Thermal problems #2—
Calorimetry—is available to complete
As is HW#3 (Molar mass practice)

There are 3 primary phases of matter (we’re
not concerned with plasmas or Bose-Einstein
condensates at this point). Describe (and
compare/contrast) each based on the
following characteristics: (use last year’s notes)
 Molecular motion (i.e. kinetic energy—quantity
and type)
 Macroscopic properties (see Word document in
“notes” section online)

Complete the following flow chart:
Energy Added
Solid
Liquid
Energy Removed

What is meant by “Latent Heat”?
How is this different than “specific heat”?
What happens to molecules of a substance
while undergoing a change of phase?
What happens to the temperature of a
substance while undergoing a change of
phase?


Sketch a heating (or cooling) curve for water,
showing the relationship between the
temperature of water and the time that passes
as thermal energy is being added (or removed)
at a constant rate
Heating curves should have proper labels
showing:
 Melting/freezing point
 Boiling/condensing point
 State of matter or process occurring during each
section of the graph



What’s the difference?
Which one occurs AT the boiling point?
Which one occurs BELOW the boiling point?

summary of the “rules” an ideal gas will
follow under this model
