Thermal Physics—Topic 3Print 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.

Warm-up:

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!)

Instructions:

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

WebAssign Problem Sets

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!

Temperature (3.1.2)

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:Resource #1 Resource #2 Resource #3

HW#1: WebAssignThermal Physics 1: Temperature Conversions

Absolute Zero

What IS absolute zero? How was it determined? What is the temperature of Absolute

Zero in the Celsius temperature scale?

Resource A Resource BResource C Resource D

Thermometric Properties

What does “Thermometric” mean? There are several examples of these

properties. List and describe each of them. Resource #4Homework #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

Calibrating (or constructing) a ThermometerResource #5 Resource #6

Resource #7 Resource #8 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)

Temperature, Heat, Thermal Energy (3.1.1, 3.1.3, 3.1.4)

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

Methods of Thermal Energy Transfer

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

Resource #12 Resource #13 (also see Resource #10)

Moles, Molar Mass, and Avogadro’s Number

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

Thermal (heat) capacity vs. Specific Heat Capacity 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

Calorimetry homework

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)

Phases of Matter

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)

Solid Liquid Gas

Phase Changes Complete the following flow chart:

Energy Added

Energy Removed

Latent Heat

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?

Heating (cooling) Curves

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

Evaporation vs. Vaporization

What’s the difference? Which one occurs AT the boiling

point? Which one occurs BELOW the boiling

point?

Kinetic Model of an ideal gas Look at last year’s notes for the

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