PHYS 202 Study Guide for Unit I (Thermodynamics)
The purpose of the study guide is to point out the most important terms, concepts, and
principles.
It is not an all inclusive panacea. The study guide is not a replacement for your
lecture note and/or you text book. Please review you notes and at least the end of the
chapter summaries. You should also review sample problems done in the lecture as well as
in the book You should also review your homework and recommended problems. The course
emphasizes problem solving.

Chapter 14: The Ideal Gas Laws
Kinetic Theory of Gases
Be able to:

Law, Gay-Lussac's Law, General Gas Law and the Ideal Gas Law
- Be able to show all the above gas laws are special cases of the ideal gas
law. i.e. Start from PV = nRT and show the other laws follow. e.g. When T is
constant PV = const , etc.

mole and a molecule
- Calculate the rms
speed of molecules given the absolute temperature.
- Define heat and absolute temperature in terms of the kinetic energy of
molecules .
- State the difference
between an ideal and real gas molecules.
- Be able to obtain
Boyle's Law and Charles' law as special cases of the ideal gas law (PV = nRT)
- State the
equipartition of energy theorem and use it to derive expressions for the molar specific
heats of monotonic, diatomic and polyatomic gases
- Be able to derive and
state the Dulog-Petit
rule and use it to calculate the specific heat (molar and mass) of
some metals such as Cu, Al, Pb, Fe, etc at room temperature
- Review examples and homework problems related to this chapter.
Chapter 15: Thermodynamics:

- Sate the four laws (Oth, 1st, 2nd and 3rd) of thermodynamics i words and
mathematically.
- Give at least three versions of the statement of the 2nd law of
thermodynamics.
