CHEMISTRY CALCULATORS
Boiling Point Altitude Calculator
Calculate the boiling point of water at various altitudes for precise scientific experiments.
What is the Boiling Point Altitude Calculator & How does it work?
The boiling point of water decreases as altitude increases due to lower atmospheric pressure. This phenomenon can be described by the Clausius-Clapeyron equation, which relates changes in temperature and pressure.At sea level (0 meters), water boils at 100Β°C. For every 300 meters increase in altitude, the boiling point decreases by approximately 1Β°C.
Delta T = frac{L}{R} lnleft(frac{P_1}{P_2}right)
Delta T = change in boiling point, L = latent heat of vaporization, R = gas constant, P_1 = initial pressure, P_2 = final pressure
Parameters
Boiling Point (Β°C)β
Frequently Asked Questions
How does boiling point change with altitude?
The boiling point of water decreases as altitude increases due to lower atmospheric pressure.
What is the formula used in this calculator?
The Clausius-Clapeyron equation: ΞT = L/R * ln(P1/P2).
At what altitude does water boil at 95Β°C?
Water boils at approximately 95Β°C around 300 meters above sea level.
How much does the boiling point decrease for every 1000 meters increase in altitude?
The boiling point decreases by about 1Β°C for every 300 meters increase in altitude.
What is the latent heat of vaporization used in this calculation?
The latent heat of vaporization (L) for water is approximately 2,257 kJ/kg.
How does temperature affect atmospheric pressure?
Temperature and atmospheric pressure are inversely related; higher temperatures generally lead to lower pressures.
Can this calculator be used for other substances besides water?
This calculator is specifically designed for water, but similar principles apply to other substances with known latent heats of vaporization.
