Factors that Affect the Boiling Point of Water ...

Thus, the boiling point of water depends on how much heat is required to vaporize the water; the amount of heat required is affected by atmospheric pressure and impurities in water. The higher the altitude, the lower the pressure, the lower the heat required, i.e. water will boil at a lower temperature.

Factors that Affect the Boiling Point of Water ...

Essentially, the boiling point of water depends on two factors: atmospheric pressure and the amount of impurities present in the water.
