Physics 313: Thermodynamics

Taught by Joanna Karczmarek


Final Exam Info and Study Aids

The Exam: Dec 11, 3:30-6pm, in room 155, Irving K Barber Learning Centre.
This will be a closed book exam. You will be provided with this formula sheet and a table of physical constants, just like on the midterm and tests.

I will be holding office hours in the week of the exam:
Monday, Dec 8, 2:30-3:30
Wednesday, Dec 10, 10:30-12:30

Last year's final is now available on WebCT Vista.

A list of review problems to help you study for the exam. If you want to see answers/solutions to any particular problem, please come to my office hours and you can look in the solution manual.

Entropy survey
Louis Deslauriers, a Research Associate in our department specializing in Physics Education is trying to understand the conceptual difficulties associated with teaching/learning about entropy. If you would like to help him out, try to answer the following two questions about entropy (without consulting your notes or the book):
(1) Please try to describe in as much detail as you can the meaning of entropy.
(2) Use the concept of entropy to explain why/how the boiling point of water changes with pressure.
You should e-mail your answers to Louis at louisd@phas.ubc.ca. In return for your participation, he will offer you some feedback on your current understanding of entropy, which might be useful for the final exam. He will not share your individual responses with me.
