The boiling point of water is the temperature at which the liquid water vapor pressure is equal to the pressure surrounding the body, and the body transforms into a vapour. The boiling point of water depends on the atmospheric pressure, which changes according to elevation. The boiling point at atmospheric pressure (14.7 psia, 1 bar absolute) for some common fluids and gases can be found from the table below: T (oF) = [T (oC)] (9/5) + 32 T (oC) = 5/9 [T (oF) - 32] Therefore, the boiling point of a liquid depends on atmospheric pressure.
