Chemistry 254  Thermodynamics I

 

LECTURES 

Tue, Thur @ 8:30-9:50 am, in STC-50

Tong Leung - Office: C2-066C (x35826) or Labs: C2-059-066 - Available any­time or by appointment.

Term tests will be conducted in the class hours.
 

TEXTBOOKS

Course and exam materials will be based primarily on Leung’s Lecture Notes Series 254 and handouts provided only in class.  It is therefore important that all the lectures are attended.  Textbook #1 is the required text of this course while the other textbooks are used as references only.
