What is the boiling temperature of water?

At sea level, the boiling point of water is 212 degrees Fahrenheit, which is equivalent to 100 degrees Celsius. However, as with any liquid, water’s boiling point fluctuates slightly due to changes in altitude.

In scientific terms, the boiling point of a liquid is the temperature at which the air pressure surrounding the liquid is equal to the vapor pressure of the liquid itself. Higher altitudes result in lower atmospheric pressure, which therefore decreases the boiling point of liquids. In Denver, Colorado, famously known as the Mile High City, water boils at approximately 202 degrees Fahrenheit. At Mount Everest’s peak, the highest point on earth, water boils at just over 160 degrees Fahrenheit.
