Aim: This is a first course in thermal physics. It covers most of the major topics in classical equilibrium thermodynamics, including thermodynamic variables, the postulates of equilibrium thermodynamics, the fundamental equation and equations of state, heat capacities and generalized susceptibilities, thermodynamic cycles, thermodynamic potentials, Maxwell relations, stability, and phase transitions.

Equilibrium thermodynamics is no longer a major area of research in itself. However, this important subject underlies many areas at the forefront of science and engineering. Some applications will be described in PHY 3513, while many more will be discussed in PHY 4523 (Statistical Physics), which covers the microscopic basis of thermodynamics.

Organization: The course will be loosely divided into three parts:
(1) An introduction to thermal physics at the high-school/early-college level. This part is designed to familiarize you with quantities such as temperature, heat, and work, and the relations between them contained in the laws of thermodynamics. We will conclude with a discussion of the concept of entropy, which plays a central role in the Part 2. Most introductory physics-with-calculus texts (Halliday, Resnick, and Walker being one example) cover this material quite adequately. However, the presentation will be designed to be self-contained, so there is no need to purchase a book for this phase of the course.
(2) A more formal development of equilibrium thermodynamics based on the `entropy maximum' postulates. This approach, which will follow Callen's book quite closely, provides an overall logical framework within which many apparently disparate results from Part 1 can be rederived from a few basic principles.
(3) More advanced formalism and applications of equilibrium thermodynamics.

Math Requirements: This course will require proficiency in (a) high-school algebra, (b) differentiation and integration of functions of one variable, (c) partial differentiation of multivariate functions, and (d) solution of simple differential equations. Items (c) and (d) will provide the greatest challenge to most students, and time will be devoted in class to these topics during Parts 2 and 3 of the course.

Homework: Problem-solving is integral to mastering any area of physics. Most weeks you will be assigned problems to be turned in the following week. You will also be recommended to attempt other problems from the text. You should make a good-faith attempt to tackle the problems on your own. However, do not spend an inordinate amount of time on any one problem. If you get stuck, feel free to discuss your conceptual or technical difficulties with other students or with the instructor. Constructive collaboration is encouraged.

Exams: There will be one mid-term assembly exam, to be held roughly halfway through the course, and a final consisting of an assembly exam plus a take-home component. The assembly exams will be conducted in a two-hour, closed-book format. The take-home part of the final will be comprehensive and open-book, but no consultation will be permitted with anyone other than the instructor.

Grade: Your grade will be assigned on the basis of an overall score, derived as follows:

homework
mid-term
assembly final
take-home final
40%
20%
