Boiling point of water

Water boils at 212 degrees Fahrenheit (100 degrees Celsius) and freezes at 32 F (0 C), right?

Sure, except that's not always true. The temperatures at which water boils or freezes can change depending on pressure and other factors.

So where on Earth do we need to go to find water's coolest boiling temperature and warmest freezing temperature?

For water's lowest boiling temperature, we must look for the place with the thinnest air.

"For water's boiling point, there is some mild dependence on humidity, but it almost all comes down to pressure," said Jacob Roberts, a professor of physics at Colorado State University.

Impurities in water affect how water molecules interact with one another, ultimately changing the point at which the whole solution comes to a rolling boil.

But if you carry a bucket of water to the top of a mountain, it will boil at a lower temperature than it will at sea level. That's because the less the atmosphere pushes on a pot of water, the less heat energy the water requir
