Quiz 9 modification

[robert zellmer]

I decided that section 10.8 (diffusion and effusion) would not be on
today's quiz.  It will be on the next one.  Don't be upset because you
studied that section for this quiz.  It will be on the next.  The next
quiz (last one, yeah!) will be 10.8-10.9, 11.1-11.5.

There's a couple of things I didn't cover in 11.4 as of yet.  I'll
send another e-mail about this.

Today's quiz will be available at noon.
