PHYSICS 180a, Fall 2000 Exam Reviews

Review for Exam 2

The second hour exam will be in OML 202 at 8:00 PM, Monday, November 6, 2000.
The exam will take 90 minutes.  You should bring a calculator. Also, you will be allowed one 8.5" by 11.0" equation sheet (both sides). A xerox of the tables on the inside covers of the text will be provided.

Review: In class on Monday 11/6/00, a selection of review problems will be available for discussion - you should email me with requests - selections of those or any other problems.

Reading covered: HRW Chapter 9-10, 13.6, 15, & 19-21.

Topics covered:

• finding center of mass
• Newton's second law relating external force and acceleration of center of mass
• changes in center-of-mass kinetic energy
• conservation of linear momentum
• impulse
• elastic collisions in 1d
• inelastic collisions in 1d
• collisions in 2d
• elasticity: Young's, shear, and bulk modulus
• pressure variation with height
• Archimedes' principle
• flow rates and Bernoulli's equation
• zeroth law of thermodynamics
• thermometers
• temperature scales: Kelvin, Celsius and Fahrenheit
• thermal expansion
• heat capacity, specific heat, heat of transformation
• first law of thermodynamics: heat and work
• ideal gas law
• relationship between v_rms and P, T and average translational kinetic energy
• E_int of ideal gas, equipartition of energy
• molar specific heats at constant V and P
• adiabatic expansion
• entropy
• second law of thermodynamics
• reversible processes
• irreversible processes: free expansion, irreversible heat transfer
• engines and refrigerators

How to study

1. Begin by making a draft of your equation sheet, based on your experiences doing the problem sets (for example, you may already know you want to include something like Table 20-4).
2. Work through the "E" review under test conditions (time pressure and looking only at the equation sheet). If you find you need to look at the text or your notes, revise your equation sheet accordingly. Check your answer in the back of the book. If you have notrouble and get the right answer, move on to the next problem or section. If you get the wrong answer or are unsure about your approach, reread the related section, try one or two other odd numbered exercises (E), then try solving the same exercise again.
3. Review the problems in PS4-PS8.3, making sure that you now know how to solve all of them correctly.
4. Finally, test your skill by solving the problems in the "P" review. It is recommended that you try these under test conditions.
