does water boil at a lower temperature at high altitude
Report Abuse. The temperature at which water boils is proportional to the pressure. The higher in altitude you are, the lower the pressure, and the lower the boiling point.... A substance boils when the temperature at which the vapor pressure of the liquid equals the pressure of the surroundings.Thus, if the pressure is 101.3 kPa, the boiling temperature will be 100C, but any change in the pressure will mean a corresponding change in boiling point.ne way to increase this kinetic energy is to heat up the molecules by raising the temperature. The reason that water boils at a lower temperature at a higher altitude is because the pressure exerted upon it from the atmosphere is less at higher altitudes and so it is less held together.
