How long does it take to boil water at different altitudes?

Does altitude affect how fast water boils?

At a higher elevation, the lower atmospheric pressure means heated water reaches its boiling point more quickly—i.e., at a lower temperature. Water at sea level boils at 212 degrees Fahrenheit; at 5,000 feet above sea level, the boiling point is 203 degrees F.

Does it take longer to boil water at low altitude?

Falling air pressure lowers the boiling point of water by just under 1 degree Fahrenheit for each 500 feet of increased elevation. The lower boiling point means water will cook off more quickly, and at a lower temperature.

Does water boil at different altitudes?

As atmospheric pressure decreases, water boils at lower temperatures. At sea level, water boils at 212 °F. With each 500-feet increase in elevation, the boiling point of water is lowered by just under 1 °F. At 7,500 feet, for example, water boils at about 198 °F.

How long does it take to boil water in Colorado?

Finding Cooking Times

Elevation Boiling Point Cooking Time
Sea Level (0 feet) 212° F (100° C) 10 minutes
2,000 feet 208° F (98° C) 12 minutes
5,000 feet 203° F (95° C) 15 minutes
7,500 feet 198° F (95° C) 18 minutes

Does water boil faster in Colorado?

Did you know that water boils quicker in Denver, Colorado than in New York City? This is because high-altitude cooking is the opposite of pressure-cooking in that the boiling point of water is lower at higher altitudes due to the decreased air pressure.

Does water boil faster with salt?

One particularly stubborn myth is that adding salt will make the water take longer to come to a boil. Chemically speaking, it’s true that salt raises the boiling point; however, the amount of salt used in cooking applications is so small that it won’t make a difference with timing.

What altitude does blood boil?

At an altitude of 63,000 feet (19,000 m), it boils at only 37 °C (99 °F), the normal body temperature of humans. This altitude is known as Armstrong’s Line. In practice bodily fluids do not boil off at this altitude.
