MCG 2130 - Thermodynamics I

Problem Labs

 

Discussion Groups :

Discussion group (problem lab) sessions will be held each week where you will solve problems.  In the problem lab, you will solve problems under the direction of the teaching assistant. In each session, the exercises will cover material currently being discussed in the lecture sessions.  At the end of each session, a test on the subject discussed in the previous week will be given.  The duration of the tests will be 20-30 minutes. Attendance is mandatory. 

There are also weekly suggested problems.  These problems will not be marked, but solutions will be available on reserve in the library and available for download on this web page.  These problems represent the minimal amount of work required to study for this course.  However, it is recommended to solve additional problems at the end of each chapter.
