A selection of songs from The Beatles (we only had time for a couple of these before today's review)
"I Feel Fine" (2:21), "Devil in Her Heart" (2:26), "Looking Through You" (2:28), "Mr Moonlight" (2:39)


The last day of class and the first of almost 3 hours of review for the Final Exam.

Today and tomorrow we will work our way through the Final Exam Study Outline.  I gave my notes to a student after class, so the figures below come from a previous class.


Dew point temperature is not shown above.  The dew point provides a measure of the amount of water vapor in the air.





Particulate matter was added to the list during today's review.  Particulate matter refers to very small particles that remain suspended in the air.  Particulates make the air look hazy and reduce visibility.  They can be inhaled and are a health hazard (small particles penetrate further into the lungs than larger particles).  Clouds and precipitation are the best way of removing particulates from the air (the sky often turns a deep blue color following a rainstorm).





Thinning of the ozone layer in the stratosphere is not the cause of climate change and global warming.  The small additional amount of UV light arriving at the ground will not cause global warming.  That UV light can cause skin cancer and cataracts, that sort of thing, but not global warming.






The tops of thunderstorms (which form in unstable air in the troposphere), the summit of Mt. Everest, and cruising altitude in a commercial airliner are all around 30,000 ft. altitude and near the top of the troposphere.


This is as far as we got in class on Wednesday. I"ll add one more section below and we'll review in tomorrow afternoon's review.


You don't need to remember the ideal gas law equations, I'll write them on the board before the start of the exam.
