At 273 K and 1 atm pressure, one mole of an ideal gas occupies
(a) Looking back at Figure 18.1, do you predict that 1 mole of an ideal gas in the middle of the stratosphere would occupy a greater or smaller volume than 22.4 L?
(b) Looking at Figure 18.1, we see that the temperature is lower at 85 km altitude than at 50 km. Does this mean that one mole of an ideal gas would occupy less volume at 85 km than at 50 km? Explain.
(c) In which parts of the atmosphere would you expect gases to behave most ideally (ignoring any photochemical reactions)?
