Thermodynamics -- Problem Set #3

Marker's Comments

Questions 1, 4 and 5 on problem set #3 were done quite well. There were a lot of 9/10's, 8/10's, 7/10's and a couple scores lower. This seemed to be an easy problem set and the student's marks didn't need to be adjusted. -Brian

Questions 2, 3 and 6: Marker's comments unavailable. -Sal
Note that we made a mistake in both the units and values for the coefficients of linear expansion for Al and Cu: they should be

Al - 23 x 10^(-6)/C
Cu - 17 x 10^(-6)/C

Among free downloads, there is an interesting and useful demo of thermodynamics available from Mount Allison University, in New Brunswick. This is a HyperCard demo, running on a Macintosh, and has lots of material included for a demo version of a commercial package at an early university level.

Included, POPTOR participants may especially be interested in sections on:
