This extended cooking time can waste precious fuel and result in undercooked meals, which is not ideal for maintaining the caloric intake required for survival in such a hostile environment. Quantifying the Pressure Drop on Everest The relationship between elevation and pressure is not linear, but it is substantial.
The Science Behind Water's Lower Boiling Point on Everest
This drastic drop is the primary reason for the low boiling point. At the base of Mount Everest, around 5,000 meters, the atmospheric pressure is roughly half of that at sea level.
At the summit of Mount Everest, the highest point on Earth, water boils at approximately 70°C (158°F), a stark contrast to the 100°C (212°F) observed at sea level. At 1,600 meters (5,280 feet), the boiling point of water drops to roughly 95°C (203°F).
The Science Behind Water's Low Boiling Point on Everest
Consequently, the vapor pressure threshold is reached at a much lower temperature. The table below illustrates the direct correlation between decreasing atmospheric pressure and the corresponding drop in the boiling point of water.
