Under what conditions of pressure and temperature do real gases most closely approximate ideal-gas behavior? (a) Name the regions of the atmosphere. (b) Why is it organized in this way? Why is the presence of ozone in the stratosphere important to us? Why does the presence of CFC"s in the stratosphere interfere with this process?
