This (short) week we have started Chapter 6, Thermochemistry. Thermochemistry is all about heat: where it is, where it's moving, how much is moving, what it does when it moves, etc. As with everything, these problems become MUCH easier with some practice, so make sure you work some examples. To help you with that, there's a new OWL assignment posted. I've included a few more simulations and other rather visual modules in this set of assignments, if you're struggling with some of these energy issues it will help to work through some of these, be sure to take advantage of these opportunities rather than just clicking through to get the right answer.
Our next exam will cover ONLY chapter 6 and is just over a week away (October 25th). Do not wait until the last minute to study. I expect a significantly better average on Exam 3, but that won't happen if you don't start working on this material this weekend.
If you need a study break, there's a football game AND a volleyball game at home today (Saturday). What happens to the kinetic energy of a wide receiver and a linebacker when they collide? When the libero gets an awesome dig and the volleyball goes straight up in the air, how are the kinetic and potential energy of the ball changing? What kind of energy is represented by the glucose molecules in the energy drinks that the players drink during the game? See? There are even fun energy problems to consider when you're watching sports...
