Additional Examples

These are older problems; most of them have solutions. Disclaimer: The solutions were made by others before us (current instructors). While the solution methods are generally sound, we are not guaranteeing that they are completely relevant, accurate, and optimal. Do NOT use these problems as reference. Use them as what they are: practice problems.

A few problems are not suitable for us because different semesters may cover some different materials; e.g. colligative property and availability/exergy were not discussed in Spring 2002. Please contact us if you have questions.
