PHYS 212 Study Guide for Test #1
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.

Chapte 19: Heat & the 1st Law of Thermo.
Be able to:

object. Good examples would be the experiments you performed in the lab to determine specific heats as well
as latent heats of fusion and vaporization.
- State the 1st Law of Thermodynamics in words and mathematically.
- State how the 1st law of thermo differs from the low of conservation of energy.
- State the thermodynamic related contributions of Count Rumford and James Joule
- Use the 1st Law in PV diagrams
- Define the processes:Quasi static, isothermal , isochoric, isobaric, adiabatic, cyclic
- Define the terms: calorie, specific heat, molar specific heat,latent heat of fusion
latent heat of vaporization.
- Calculate work done by an ideal gas undergoing an isothermal , isobaric and /or adiabatic process
- State the three means of heat transfer and explain how they are incorporated in the design of a thermos bottle.
- Explain why sea breezes blow from sea to land during a hot summer day and from land to sea in a cool night.
Extend your reasoning to monsoon rains and mountain and valley breezes.
