We have provided the simple steps to find the boiling point, boiling point elevation formula and solved examples on this page.
Following is the step by step process to evaluate the water boiling point.
In chemistry, the boiling point is the temperature where the liquid vapour pressure equals the external pressure surrounding the liquid. At this temperature, the liquid is converted into a vapour state. The boiling point elevation is the increase in the solvent boiling point by adding the solute. This temperature is dependant on the pressure.
The normal boiling point of the seawater is -100°C or 212°F. In the same way, the freezing point of the water at sea level is 0°C or 32°F.
We know that water boiling point depends on the pressure and pressure depends on the altitude at the sea level. The formulas to calculate the pressure, the boiling point is given here:
boiling point = 49.161 x log(pressure) + 44.932
pressure = 29.921(1 - 0.0000068753 x altitude)5.2559
Question: Find the boiling point of water located at 2500 m altitude.
Altitude = 2500 m
convert 2500 m into ft
1 m = 3.28084 ft
altitude = 2500 x 3.28084 = 8,202.1 ft
Pressure = 29.921(1 - 0.0000068753 x altitude)5.2559
= 29.921(1 - 0.0000068753 x 8,202.1)5.2559
= 29.921(1 - 0.05639189813)5.2559
= 22.05 in_Hg
Boiling Point = 49.161 * ln(pressure) + 44.932
= 49.161 x ln(22.05) + 44.932
Therefore, the boiling point of water is 197.01°F.

1. How to calculate water boiling point?
Before computing the boiling point, we need to find the pressure of the water. The formula to get the pressure is pressure = 29.921(1 - 0.0000068753 x altitude)5.2559. Multiply the log of pressure with the 49 and 45 to it to check the boiling point.
2. What are the factors that depend on boiling point at elevation?
The boiling point of water at altitude depends on the pressure and it depends on the altitude. By increasing the altitude, the boiling point decreases.
3. What is the boiling point elevation equation?
The water boiling point formula is boiling point = 49.161 x log(pressure) + 44.932.
4. What is the boiling point altitude of 50 m?
altitude = 50 m = 50 x 3.28084 = 164.042 ft
Pressure = 29.921 x (1 - 0.0000068753 x altitude)5.2559
= 29.921 x (1 - 0.0000068753 x 164.042)5.2559
= 29.744059 in-Hg
Boiling point = 49.161 x log(pressure) + 44.932
= 49.161 x log(29.744059) + 44.932
Therefore, the boiling point of water is 211.71°F.
