Description of the Course

This is an intermediate level course on classical and statistical thermodynamics.
It covers the topics of temperature, heat, ideal gases, the laws of thermodynamics,
phase transitions, calorimetry, entropy, thermodynamic potentials, Boltzmann statistics,
quantum statistics, Fermi gases, and blackbody radiation.

Grades

Grades will be based on the class participation, problem assignments and four exams as follows:

Undergraduates:

Best exam scores -- 50%
Second lowest exam score -- 20%
Lowest exam score -- 10%
Homework -- 20%

Graduates:

Exam I -- 20%
Exam II -- 20%
Exam III -- 20%
Homework -- 40%

All tests must be taken on the scheduled date.
Makeup tests will ONLY be given under rare circumstances, in case of an emergency ocurring prior to or on the exam date. Prove of absence will be required.

Course Grade Point Scale
A+ = 97-100, A = 93-96, A- = 90-92
B+ = 87-89, B = 83-86, B- = 80-82
C+ = 77-79, C = 73-76, C- = 70-72
D = 60 - 69, F < 60

Official Grade Policy by CUA can be found on:
Undergraduate Grade Policy
Graduate Grade Policy


Homework Assignments

Homework will consist of reading from the text and problem assignments. It is generally advisable to carry out the reading before the corresponding material is discussed in lecture. The problem assignments can be downloaded in the course outline above.

Late assignments will ONLY be accepted under rare circumstances, in case of emergency.
While collaboration on homework assignments is allowed, simply copying work from another student is NOT allowed and will be considered cheating.
