The boiling point of water is 100 degrees c, but only at sea level, or in other words, at an atmospheric pressure of 1013.2 millibars. The boiling point of pure water at sea level atmospheric pressure (1 atm or 101.325 kpa, 760mm hg) The boiling point of water decreases as elevation increases At 4500 meters above sea level, the boiling point of water is around 85°c (185°f) due to the lower atmospheric pressure. The boiling point of water decreases at higher altitudes because the atmospheric pressure is lower. Boiling point of water is inversely proportional to atmospheric pressure, which depends on altitude and weather
Higher altitude, lower boiling point Water boils at 100 c at sea level The boiling point of a liquid is defined as when the vapour pressure of that liquid is equal to the atmospheric pressure On mountains, the air pressure is lower than at sea level, so it follows. The boiling point of water decreases at higher altitudes because the atmospheric pressure is lower At lower pressure, molecules in the water can escape into the air more easily, requiring less.
Kelvin temperature scale indicates a boiling water temperature of 373º. The dead sea is below mean sea level for the earth Therefore, the pressure at the dead sea would be greater than at mean sea level and the boiling point of water would be above 100c.
