Time for one complete selection from 2 Cellos, "Mombasa", before the start of the last class of the semester.
Today was devoted to reviewing for the Final Exam.  The exam for this section is on Friday this week, but you have the option of taking the exam with the other section (please let me know if you plan to do that).  Their exam is scheduled for Wednesday next week from 10:30 am - 12:30 pm in McClelland Park 105.

We were able to get through the first 5 topics and most of the 6th topic on the Final Exam Study Outline today .  The figures below are from a previous semester. 








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 in class.  Particulate matter refers to very small particles that remain suspended in the air.  Particulates make the air look hazy and reduce visibility.  The sky today is still somewhat hazy after the windy weather yesterday. 

Particulates 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.





You don't need to remember the ideal gas law equations, I'll write them on the board before the start of the exam just like was done before the quizzes this semester.



I didn't have time to mention Archimedes Law at the review today.  That's where we will start at the review tomorrow.
