Old IB Thermodynamics Test

Don't study this - this is an old test.

Whatsonna Chapter 13, 14, 15 Test .:. Review PowerPoint .:. Go up

Prequizzes solved: 13.1 | 14.1 | 15.1 |  Ideal Gas Law

Do 3 out of 4 pages:

1Ideal Gas Law: (This page is pretty tough - fair, but tough.  I think it is a bit harder than the skill set.   Don't try it unless you are pretty good at both the ideal gas law (converting units of pressure, Kelvins, calculating mols, gauge pressure, etc, AND the combined gas law))

A) Ideal gas law (PV = nRT) - (13:35, PQ13.1#2) Ideal Gas Example 1

B) Ideal gas law (PV = nRT) - (13:31, PQ13.1#2) Ideal Gas Example 2

C) Ideal Gas Law Question - (Ideal #5, PQ13.1#3) Ideal Gas Example 3

D) PV/nT = PV/nT - (Ideal #6, PQ13.1 #5) Combined Law Example 2

E) PV/nT = PV/nT - (Ideal #8, PQ13.1 #4) Combined Law Example 3

2. Phase change graph, Just W14:26-33 and PQ14.1 (This page is not harder than the skill set - it is the same...)

A) Graph reading question.  (Where is the solid, liquid, ... etc.)  (PQ14.1#1) Phase Change Graphs

B) Graph reading and kinetic vs potential energy (W14:26, 30) Phase Change Graphs

C) Specific heat 14:9 (read values from graph) - (PQ14.1#3, W14:28, 32) Specific Heats from Graph

D) Latent heat 14:23 (read values from graph) - (PQ14.1#2, W14:29,33) Latent Heats from Graph

E) Heat needed to bring from below boiling to some temp above boiling - (PQ14.1#4) Latent Heat Example 3

3. pV diagram of a cycle (like PQ15.1, and W15:26 (worksheet 15, problem 26))  This is just like the skill set, except for E) which is from 13.1

A) Temperatures of vertices - (PQ15.1#1, W15:26cde) (Use pV=nRT, read p and V from graph  OR use combined gas law)

B) Work done for a complete cycle - (PQ15.1#4) - (W15:26a, PQ15.1#3) PV Cycles Example 1

C) calculate mols - (Ideal #3, W15:26b) (Use pV=nRT, read p and V, and I tell you T - it's like W15:26)

D) Heat flow, work, and internal energy questions (Q = U + W) Q = U + W Example 2, Q = U + W Example 1 Q = U + W Example 3 (Everyone gets this wrong - so you might want to view the explainy video Heat engine problems Q = U + W)

E) Pressure = Force/Area    problem - (PQ13.1#1) Pressure Example 4 (Remember the area of a circle is r2)

4. First law of thermodynamics (Energy is conserved) (This page is not too hard, but you do need to answer a couple of conceptual questions with words.  Be sure you can explain briefly the four modes of heat transfer we talked about for D), and C) is pretty much common sense)

A) Potential energy turning to heat (W15:1)  First Law Problems(4:00),  First Law Example 1

B) Kinetic energy turning to heat (W15:2) First Law Example 2

C) Conceptual question about conservation of energy. (Read Ch 15.1)

D) What are at least three methods of heat transfer? - (Read Ch 14-7 through 14-9 in your textbook,  or look at your notes from the day I talked about heat transfer) HeatTransfer.ppt

E) Calorimetry - (W14:20, PQ14.1#5) Calorimetry Example 2
