Physical Chemistry Guide: Altitude & Boiling Point
A liquid boils when its internal vapor pressure equals the surrounding atmospheric pressure. Because air pressure decreases with altitude:P = P_0 × (1 - 2.25577 × 10⁻⁵ × h)^5.25588Water boils at ~1°F lower for every 500 feet of elevation gain.
Frequently Asked Questions
?What is the boiling point of water in Denver, Colorado?
At Denver's elevation of 5,280 feet (1 mile high), atmospheric pressure is ~0.83 atm, causing water to boil at approximately 202.5°F (94.7°C).
