2. At T = 0, the standard translational partition function, qt, = V/ $\Lambda ^3$ , and standard rotational partition function, qr, = T⁄Θr, are not valid.

a) Why? What important low-T behavior do they get wrong?

b) What are the true values of qt and qr at T = 0? Why?

c) Why are we using wrong expressions, how did this problem come about?

e) Does the vibrational partition function have the same problem? Why or why not?

d) How could the problem be fixed for doing calculations at very low T?

A Routine Endoscopic Procedure Our mother usually had an endoscopic procedure every 2 years. We thought that she had too many visits with her gastroenterologist. She saw the gastroenterologist about every 30 or 60 days. When we asked the physician why our mother had to come in on a continuous basis, his response was “acid reflux.” She was taking a proton pump inhibitor for her acid reflux. Our mother had an endoscopy of her upper gastrointestinal tract in September 2006....
