Honor Code
Homework that is submitted to be graded should be your work alone. While you are encouraged to work with
others (during office hrs or elsewhere) in understanding the material of each homework problem, it is illegal to copy homework
from others or from other sources (e.g. solution manual).
Failure to follow these restrictions, and giving or receiving unauthorized aid or assistance on
exams are Cornell honor system violations and cases will be filed.

Exams
Policy for make-up exams: If there is a documented conflict with another exam, we will
provide a make-up exam 2-3 hours before our regular exam. We strongly discourage you from requesting a make-up exam
at another time and day. This way all students take the same exam and issues of varying degree of difficulty
between exams do not arise. We will work with each of you case-by-case if there is an unexpected `emergency'.
We are very sorry if the days of the exam (including the final) are not convenient to your overall (travel) plans.
Failure to take any of the exams will result in an automatic loss of grade.

Frank H. T. Rhodes Hall.
Teaching Assistants:
HW or exam re-grading: The grader for the class is Hon C. Hoi. For regrades, please submit your HW or prelim within two days after its return to you to any of
the TAs during office hours or in your recitation. No regrades will be considered after that time. Be sure to attach to your HW/prelim
a clear statement explaining what you need to be regraded and why.
Office hours:
You are encouraged to attend the office hours of any of the TAs and not only of your recitation TA. The office hours can be
of much higher benefit if you already have spent some time working the HW problems and you
come prepared to ask the right questions.
- Mondays: 4:00-5:45 pm (Rhodes 151).
All TAs are available to meet with you at this location
for a one-to-one advising basis (Email your TAs two days in advance
to arrange for such meetings). Please take advantage of this unique opportunity.
- Tuesdays: Professor N. Zabaras, 4:00-5:30 pm (Rhodes 151).
- Wednesdays: Kobbina Awuah,
5:00-7:00 pm (Rhodes 151).
- Thursdays: Professor N. Zabaras,
3:15-4:15 pm (Rhodes 151) and Roland Florenz, 4:15-5:30 (Rhodes 151).
- Saturdays: Xiang Ma and Kobbina Awuah,
5:00-7:00 pm (Rhodes 178).
- Sundays: Iris Choi, Roland Florenz & Yuan Chew,
5:00-7:00 pm (Rhodes 178).
Exam Schedule:
Closed books & notes. You need to be able to derive simple
formulas using the fundamental laws of thermodynamics. Some formulas and Tables will be provided as needed.
Only simple calculators will be allowed in the exam for manipulating data. Electronic and wireless communications
are serious violations of the course policy and prohibited.
- Exam 1: 10/11/2007, 7:30-9:30 pm, OH 155.
- Exam 2: 11/15/2007, 7:30-9:30 pm, OH 155.
- Final Exam: Fri, Dec 7, 2:00 - 4:30 pm, HO B14.
Required textbook:
Optional references:
Homework: assigned each Monday evening on the course web site and due the following Monday by 5 pm in
the designated homework box in Upson 123 (the small room leading to the Upson Lounge kitchen). Be sure that you
indicate your recitation section (and your name!) on the top of the first page of your HW. We will not
accept late homework -- if there was a serious reason for that please talk to Prof. Zabaras as the TAs are not authorized to
accept late HWs. Homeworks will be returned in your recitation. The TAs have been instructed to keep your HW for only one
extra week in case you miss a recitation.
Working on homework: You are
strongly encouraged to work and discuss the homework in small groups during and outside office hours and recitations.
It is more important to
understand the theory and methodology needed to solve each HW problem rather than receiving a good HW grade!!
Grading: Homework 20%, two prelims 40%, and final exam 40%.
Prerequisites: Calculus for Engineers (MATH 192), Physics I: Mechanics (PHYS 112).

Course description
The definitions, concepts, and laws of
thermodynamics. Applications to ideal and real gases, vapor and gas
power systems and heat pump systems. Combustion,
chemical equilibrium, chemical kinetics and phase transitions. The course will introduce students to real world energy systems
and develop analysis techniques for these systems. A systematic problem solving process will be emphasized.
Course objectives:
- understanding of thermodynamic principles
- apply the first and second laws of thermodynamics
- understanding of the basic relations among physical
properties of materials
