What is the Boiling Point of a Sea Water?
Boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature.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. Specific units of boiling point, pressure and altitude are as follows.
- Boiling point is in degrees Fahrenheit (°F);
- Pressure is expressed in inches of mercury (inHg)
- The altitude imperial unit is feet (ft).
Boiling Point Altitude - Formula
The boiling point of a water depends on the pressure and pressure depends on the altitude at the sea level. The formula for boiling point, the pressure is Boiling point = 49.161 * ln(pressure) + 44.932 Pressure = 29.921 * (1 - 0.0000068753 * altitude)^ 5.2559

Boiling Point Altitude Examples
1. Find the boiling point of water located at 2430m altitude?
Given that ,
Altitude = 2430 m
convert 2430m into ft
1 m = 3.28084 ft
altitude = 2430x 3.28084 = 7970ft
pressure = 29.921 * (1 - 0.0000068753 * altitude)^ 5.2559
= 29.921 * (1 - 0.0000068753 * 7970)^ 5.2559
= 29.921 * (1 - 0.054796141)^ 5.2559
= 29.921 * (0.9452038)^ 5.2559 = 22.25inHg
Boiling point = 49.161 * ln(pressure) + 44.932
= 49.161 * ln (22.25) + 44.932
=49.161 *1.347 = 197.44°F
Therefore, the boiling point of water is 197.44°F.
2. Find the boiling point of water located at 3000m altitude?
Given that ,
Altitude = 3000 m
convert 3000m into ft
1 m = 3.28084 ft
altitude = 3000x 3.28084 = 9842ft
pressure = 29.921 * (1 - 0.0000068753 * altitude)^ 5.2559
= 29.921 * (1 - 0.0000068753 * 9842)^ 5.2559
=29.921 * ( 0.93233)^ 5.2559 = 20.70inHg
Boiling point = 49.161 * ln(pressure) + 44.932
= 49.161 * ln(20.70) + 44.932 = 109.62°F.
Therefore, the boiling point of water is 109.62°F.
FAQs on Boiling Point Altitude Calculator
1. 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.
2. What is the relationship of altitude and boiling point?
At a higher elevation, the lower atmospheric pressure means heated water reaches its boiling point more quickly at a lower temperature.
3. What is the formula for boiling point and pressure?
The formula for Boiling point = 49.161 * ln(pressure) + 44.932
The formula for pressure = 29.921 * (1 - 0.0000068753 * altitude)^ 5.2559
4. What are the units of boiling point, pressure and altitude?
Boiling point is in degrees Fahrenheit (°F);
pressure is expressed in inches of mercury (inHg)
