Vapor PressureThe vapor pressure of a substance describes how readilymolecules at the surface of the substance enter the gaseousphase. At the boiling point of a liquid, the liquid's vapor pressureis equal to or greater than the atmospheric pressure exerted onthe surface of the liquid. Since the atmospheric pressure at higherelevations is lower than at sea level, the boiling point of waterdecreases as the elevation increases. The atmospheric pressureat sea level is 760 mm Hg. This pressure decreases by 19.8mm Hg for every 1000-ft increase in elevation.Elevationo ft1000 ft2000 ftPressure760mmHg740.2mmHg720.4mmHgThe boiling point of water decreases 0.05° C for every 1 mmHgdrop in atmospheric pressure.Part AWhat is the boiling point of water at an elevation of 1.70×104 ft ?Express your answer with the appropriate units using three significant figures.► View Available Hint(s)T = 93.07SubmitμÅProvide FeedbackPrevious Answers°C?X Incorrect; Try Again; 2 attempts remaining

Question

Vapor Pressure
The vapor pressure of a substance describes how readily
molecules at the surface of the substance enter the gaseous
phase. At the boiling point of a liquid, the liquid's vapor pressure
is equal to or greater than the atmospheric pressure exerted on
the surface of the liquid. Since the atmospheric pressure at higher
elevations is lower than at sea level, the boiling point of water
decreases as the elevation increases. The atmospheric pressure
at sea level is 760 mm Hg. This pressure decreases by 19.8
mm Hg for every 1000-ft increase in elevation.
