1. As we study transport processes, we're considering three different examples -- diffusion, thermal conductivity, and viscosity. What quantities are "transported" in each of these three cases?
Now, lest we forget to apply these concepts to something in the real world, consider a Thanksgiving Day turkey that needed to be cooked. How, if at all, were each of our three transport processes involved in preparing that Thanksgiving turkey?

2. What's the approximate order of magnitude of the viscosity, h, of air at room temperature and atmospheric pressure? Be sure to include your units for the viscosity. (What are the fundamental units in a poise, the cgs unit for viscosity?)
3. In the humble opinion of your instructor, our text doesn't do as good a job explaining "generalized forces" as is possible to do. We'll discuss this idea further in class. For now, though, consider that we generally think of the work being done by (on) a system as
Which of the following would NOT be an example of a generalized force and changing parameter combination that results in work being done by (on) a system?
Check the correct answer: a) mechanical force (F), position (dx)b) pressure (P), volume (dV)c) charge (q), electric potential (dV)d) gravitational force (Fgrav), mass (dM) Below is a space for your thoughts, including general comments about today's assignment (what seemed impossible, what reading didn't make sense, what we should spend class time on, what was "cool", etc.): You may change your mind as often as you wish.
