The atmosphere is a sensitive indicator of human perturbations to the environment. In the last 30 years, global environmental catastrophes such as the ozone hole, smog, and global warming have affected our ability to live in and breathe the air around us. To understand the atmosphere and changes to it, we first investigate the properties of gases. We have already discussed changes in atmospheric composition due to increases in man-made emissions of species such as greenhouse gases. It is also possible, however, to change the composition of the atmosphere by changing its chemistry. We will next investigate the nature of these changes and how they lead to such problems as the ozone hole and smog.
For Monday, Mar. 22: Begin reading the articles assigned for Wednesday. Review Sections 6.3 - 6.6 (pp. 246 - 270) in your textbook and begin the problems assigned for Wednesday. We will review similar problems in discussion on Monday. Examples can include Chapter 6, #6.3, 6.5, 6.13, 6.31, 6.35, 6.40, 6.44, 6.46, 6.59, 6.69, 6.79, 6.83, 6.85, 6.89, 6.94, 6.96, 6.99, 6.103, 6.107. It will be helpful if you have looked over these problems and identified the ones you have difficulty solving.
For Wednesday, Mar. 24: Please read Morell, “Ahead in the Clouds,” and Grossman, “Laughing Gas is Biggest Threat to Ozone Layer,” both posted in E-reserves.
Complete the following problems from your textbook: Chapter 6, #6.4, 6.12, 6.32, 6.36, 6.43, 6.60, 6.70, 6.80, 6.88, 6.90, 6.100, 6.104, 6.108.
For Friday, Mar. 1: There will be no class held on Friday because I have a schedule conflict.
