At what temperature does water boil at the top of Mt Everest?

68°C (154.4°F)
101,4°C (213,8°F)
100°C (212°F)
98,6°C (208,4°F)
The boiling point of water depends on the pressure. On top of Mount Everest, the pressure is about 260 mbar (26.39 kPa) and the boiling point of water is 69 °C. (156.2 °F). In contrast, water can still remain liquid near deep hydrothermal vents, even if the temperature is very high.
