As a result, the boiling point of water is lower on tall mountain peaks.
For example, on top of Mount Everest, at 8,848 m (29029 ft) elevation, the pressure is about 34 kPa (255 Torr) and the boiling point of water is 71°C (160 °F).
The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
