Review
The examination is scheduled for Tues., Dec. 4. The exam will have two sections,
that is, it will follow a format similar to the last examination. During the problem
solving part, you will again be provided with a sheet of equations that you may need
to solve a particular problem but you may be asked to derive an eqn. in one or more
instance. There will be more eqns. than you need. You will be expected to know
basic equations like the ideal gas law. If you set up the problem correctly you will
get major credit.
The review sheets follow. They are words and concepts that should be very familiar
to you. As before, I will take the multiple choice questions from these sheets. Also
the problem solving will be problems based on concepts taken from problems
assigned for homework, given on a quiz, and listed on the review sheets.
Definitions: (The meanings of these words and phrases should be very familiar.
