The rate of change of atmospheric pressure P with respect to altitude h is proportional to P, provided that the temperature is constant. At a specific temperature, the pressure is 103.8 kPa at sea level and 89.3 kPa at h = 1,000 m. (Round your answers to one decimal place.)

(a) What is the pressure at an altitude of 4500 m?

(b) What is the pressure at the top of a mountain that is 6551 m high?

The equation relating approximate barometric pressure (P, in torr) to altitude (h, in m) at room temperature (T, °C) is ln P = 6.63 – (h/8000) Diethyl ether, CH3CH2OCH2CH3, a common organic solvent, has a normal boiling point of 34.6 °C (and thus a vapor pressure of 760 torr at 34.6 °C). At 25 °C, it has a vapor pressure of 532 torr. At what approximate altitude will diethyl ether boil at 25 °C? Where on Earth would it be...
