Thursday, 12-2

Exam Tomorrow! Covers Work, power, percent efficiency, machines, etc. AND new material on Thermal Energy. (Chapter 6 and chapter 9, section 1-3)

I handed out a list of topics for the full semester today and the back side is all focused on this exam. If you missed it, there is a link to it under Monday or Tuesday's post. Good idea to start studying; we have a comprehensive exam at the end of the month PLUS a final. Everyone takes the comprehensive exam. Final depends on attendance, and is optional if you don't have to take it.
Today we finished notes in some classes on convection, conduction, and radiation, discussed some of last night's reading, some classes had a pop quiz, and we saw demonstrations on:

-Is water a conductor? (what happens when you heat it from the top?) (bottom stays cool - no, not a very good conductor... we will see if it conducts electricity later...)
-radiation with a radiometer
-insulating values of a styrofoam cup vs. paper
-bimetallic strips and thermal expansion
-ball and loop
Tomorrow you'll learn the magic of the drinking bird phenomenon that seems to go on forever.
Want study materials??
Here's a T/G/T review that we didn't do in class but you can do on your own: here
