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. Elevation Pressure o ft 1000 ft 2000 ft 760 mmHg 740.2 mmHg 720.4 mmHg The boiling point of water decreases 0.05°C for every 1 mmHg drop in atmospheric pressure.
