Pure water boiling point
WebPure water boils at 100 0 C (at 760 mm of mercury pressure). At high pressure, the boiling point is more than 100 0 C. when pressure is high, molecules of water vapour cannot escape easily from the surface. This is why food cooks faster in a pressure cooker. At low pressures (or on high mountains), water boils at a temperature slightly less than 100 0 C.
