When you think of Heat, Thermal Energy, and

Temperature, what comes to mind?

3 min: write on your own warm-up sheet…one of your last few

entries for 1st semester

Thermal Physics—Topic 3Print off topic outline by tomorrow.Test on this unit will be Friday, Feb. 8, 2013

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 nearly every day for this unit. Bring one or share one.

All questions in this PowerPoint should be considered as things you need to answer. Answer them in your notes and/or syllabus statement book (under the proper statement) as if they were a worksheet to be turned in.

Packet Turn-in—all due Friday, February 8, 2013:

Clear work from each of the WebAssign problem sets (there are 4 of them!)

Calorimetry Lab (CE and analysis questions) Please remember to attach the CE scoring sheet

Gas pressure lab (DCP) Please remember to attach the DCP scoring sheet

Thermometric Properties Design lab Please remember to attach the Design scoring sheet

Topic 3 Syllabus Statements—thoroughly completed using the notes/questions/resources found in this power point and the other supplemental notes posted.

Content that will be on the Sem. 1 Final exam:

Syllabus statements 3.1.1-3.1.4 (which covers slides 7-13)

Every other slide will NOT be on the semester 1 final exam. For the next week or so, focus on the first 13 slides.

When 2nd semester begins, we’ll pick up with slide 14 and continue with the syllabus

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. We will be going over clarifying questions and practice problems in class. You MUST read notes ahead of time on your own!

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 the day of the exam

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 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. 8, 2013)

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—score checklist will be posted soon.

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)

Demonstrations related to slides 5-10

Take notes on each of the demos completed and discussed in class. I promise they are each somehow related to one or more of your syllabus statements. (unless told otherwise )

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

Lab: Calorimetry

Will be completed in class Purpose: to determine the identity of an

unknown metal based only on the calculation of its specific heat capacity.

This will be a CE lab, but there will also be some analysis questions to assist you in processing your data. You will be receiving a procedure and collecting data in class, and you will be writing a conclusion discussing your results.

Calorimetry homework

HW reminder! Calorimetry lab (data table and analysis questions A-F) due on

Friday, 2/8/2013!Sample Problems: there is a Word Document posted 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) and #4 (phase changes)

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?HW reminder! WebAssign #4 (Phase

changes and Gas Laws) is available.

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 your teacher know…)

How is molecular molar mass determined?

What is Avogadro’s number? Where did it come from?

Resource #14 Resource #15

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

Gas Laws: Boyle’s law (this was your lab last week)▪ Resource #16 Resource #17

Charles’ Law▪ Resource #18

Combined Gas law▪ Resource #19 (pHet simulation)

Lab 2: Pressure vs. Volume of a gas

Individually collected data Equipment will be available at the

beginning of 2nd semester. Data collection must be completed

by Monday, Feb. 4. Equipment will NOT be available

after Monday, Feb. 4 DCP will be due on the day of your

exam (Friday, Feb. 8)
