Answer #1

According to the problem;

This pressure decreases by 19.8 mm Hg for every 1000- ft increase in elevation.

Total pressure drop at 1.55*10^4:

19. 8 mm Hg / 1000 ft * 1.55 x10^4 ft = 306.9 mm Hg

The boiling point of water decreases 0.05 C for every 1 mm Hg drop in atmospheric pressure.

Total temperature drop = 0.05 deg C / 1 mm Hg * 306.9 mm Hg = 15.345 deg C

Boiling point = 100 – 15.345 = 84.655 deg C

    "Vapor Pressure of Water" assignment: VAPOR PRESSURE OF WATER INTRODUCTION All liquids exist in equilibrium with the vapor state. As temperature increases, this equilibrium shifts more and more in favor of the vapor until one reaches the boiling point, at which all liquid is converted to gas. The pressure exerted by the vapor over the liquid is known as its vapor pressure and is a function of temperature. Boiling occurs at the temperature at which the vapor pressure is equal...
