Chapter 18, Problem 36P
(II) When using a mercury barometer (Section 13–6), the vapor pressure of mercury is usually assumed to be zero. At room temperature mercury’s vapor pressure is about 0.0015 mm-Hg. At sea level, the height h of mercury in a barometer is about 760mm. (a) If the vapor pressure of mercury is neglected, is the true atmospheric pressure greater or less than the value read from the barometer? (b) What is the percent error? (c) What is the percent error if you use a water barometer and ignore water’s saturated vapor pressure at STP?

The air pressure supplied to a scuba diver must equal that exerted by the surrounding seawater, and for each 10 m increase in depth,pressure of the surrounding seawater increases one full atmosphere. Assuming the partial pressure of oxygen in air at sea level (one at-mosphere) is 0.209 × 760 mm Hg (= 159 mm Hg), what partial pressure of oxygen would a diver be breathing at a depth of 30 m?
The rate of change of atmospheric pressure P with respect to altitude h is
proportional to P, provided that the temperature is constant. At 15°C the pressure is
101.3 kPa at sca level and 87.14 kPa at h = 1000 m.
