Some Notes on Homework #6

Problem 28

When calculating the percent error, compare your calculated enthalpy at 25 °C to the tabulated value at 0 °C (1189.5 J/g). Please ignore the fact that this tabulated value is not at the same temperature as your results. You do not need to rescale the tabulated value to 25 °C.

Problem 31-b

For this problem, assume that no phase changes occur - all components remain gases over all temperatures. Also assume that the heat capacity coefficients given in Appendix C.1 are valid over all temperatures. There is a typo in the problem, so don't worry if your answer seems off, just approach the problem the same way you've learned in class.

Monday morning office hours cancelled

I have a conflicting appointment tomorrow and won't be able to keep my office hour Monday morning. If you have questions on the homework, please email me, stop by my office (Eng. II, room 3218), or come to Anthony, Kate, or Prof. Shell's office hours. I apologize for any inconvenience.

Review sessions

Dear class,

Midterm exam

Dear class-

To summarize what we discussed today in class, the midterm exam will be on Friday, February 4th in class. You will have approximately one hour to work the exam, which will cover Chapters 1-3 in the book. Bring a pencil and calculator. The exam will be open book, but closed notes. HOWEVER, you may bring one 8.5 x 11" page of handwritten notes, front and back. This should give you the opportunity to organize the course equations for quick reference during the exam.

Also, note that HW5 is not due until Monday, February 7.

Cheers,
MSS

Lost calculator

Did anyone leave a calculator in class today? One was turned in to me. Please contact me if you believe it is yours, and let me know what type of calculator it is.

Cheers,
MSS

Office hours update and HW2 solutions

Dear class,

The office hour time on Mondays that was 5-6pm has been moved to 6-7pm because of a room schedule conflict.

Also, solutions to HW2 can be found on the course webpage.
