Class Hours: Tuesday, Thursday: 1:40 3:00 pm, ARC-110 Instructor: M. J. Matthewson Office: Engineering A133 Telephone: 848-445-5933 E-mail: to mjm: [email protected]

to entire class: [email protected] Note: If I send email to [email protected] I assume you have read it. It is therefore your responsibility to check your email regularly, to make sure communications from sakai are not treated as spam, and to ensure that sakai has the best email address for contacting you.

Web: sakai.rutgers.edu to access this web site you must either be registered for the course or be given access by Professor Matthewson. Notes, assignments, solutions, grades, schedules etc. will all be published here.

Schedule: The schedule is available on sakai.rutgers.edu. Office Hours: I operate an open door policy - if I am in, I will be glad to talk to

you. However, I also have formal office hours so that you know when you can find me in: Monday 1:00-2:00 pm and Tuesday, Thursday 3:00-4:00 pm. In addition, you can arrange an appoint-ment to meet me by e-mail. Please avoid coming to my office in the half hour or hour before class.

Textbooks The book that most closely follows the course (or vice versa) is Thermodynamics of Solids Second Edition, Swalin (Wiley) (the first edition is quite similar), but this is more of a reference than a text book. This book is out of print and new copies can be upwards of $200 (although used copies are often much less, so keep checking Amazon). Be aware that used copies of the “second edition” might turn out to be the first edition. Given the problems with obtaining Swalin, I recommend as an alternative Introduction to the Thermodynamics of Materials, Gaskell (Taylor & Francis), currently in its fifth edition. It is well known and has been the undergraduate class text in our department so is readily available. However, it does not cover thermodynamics of defects, so I will post suitable notes on sakai. Thermodynamics in Materials Science, 2nd Ed., Robert DeHoff (CRC) is a relatively new book (which has also been used as an undergraduate text in our department) that takes a slightly different approach to the subject. Thermodynamics of Materials Vols. I & II, Ragone (Wiley) is perhaps my favorite since both

volumes are very well written, but they are two books ($) and the notation can sometimes be a little confusing. Note that, while there are many thermodynamics textbooks, few consider the thermodynamics of defects and usually do not pay much attention to issues related to materials science. Grading The grade for this course is made up of 6 problem sets (20%), 2 quizzes (40%) and a final exam (40%). Problem sets should be individual efforts but students are encouraged to help each other. Handing in any work copied from other students is unacceptable and will be treated as cheating. The quizzes and the final exam are all closed book.

Calculators will be provided for quizzes and the final - if students want to use their own calculator, they must demonstrate clearing the calculator’s memory at the start of the exam - please come early if you choose to do this. Students should bring graph paper and a ruler to the quizzes and final exam. Academic Integrity I, like my colleagues and Rutgers as a whole, take academic integrity very seriously. All students should be aware of our policies for academic integrity, which can be found at http://academicintegrity.rutgers.edu. I will assume that all students are familiar with the rules and are therefore fully culpable for all and any infractions.

Note especially for this course, students should not obtain or use old exams (class exams or PhD qualifier exams) or problem sets or solutions from this course, unless with my explicit permission (or Professor Klein’s permission for the qualifiers). Having such material will be an unfair advantage over your colleagues who do not have the same access; therefore I consider it cheating to possess or use such material. I will not handle any cases of cheating myself, but will promptly report them to the relevant Dean. Course Outline 1. The Laws of Thermodynamics Systems, thermodynamic variables. 0th Law: temperature scales. 1st Law: heat and work, internal energy, enthalpy. 2nd Law: reversibility, efficiency, heat engines and pumps, thermodynamic scale of temperature, irreversible processes, entropy, calculations of entropy changes, Maxwell relations. Relationships between thermodynamic properties: specific heat, perfect gas, relationship to interatomic potentials, empirical relationships. Free energy and quilibrium: maximum useful work. Third law. e

2. Statistical Mechanics Microscopic interpretation of entropy: Gibbs paradox, Boltzmann hypothesis, principal of equal a priori probability, distinguishability, Boltzmann distribution, examples of its use. Temperature

ependence of heat capacities: equipartition theorem, Einstein's model, Debye theory. d 3. Chemical Thermodynamics Order of phase transition. First order reactions: Clapeyron, effect of external pressure. Chemical reactions: standard state, non-standard state, fugacity and activity. Ellingham diagrams: basis, uses,

2Op control. Thermodynamic tables: JANAF, TAPP, meaning of quantities, examples of ses, thermochemical diagrams. u
