Question: Where is liquid nitrogen found?

Hi @lablablabmax9, you won’t find liquid nitrogen naturally anywhere on Earth because liquid nitrogen’s boiling point on Earth’s surface is -196 degrees celsius. This means that it boils off as soon as it is exposed to normal atmospheric pressure. Some scientists think liquid nitrogen might exist naturally on Triton, one of Saturn’s moons. A lot of scientific labs use liquid nitrogen for their experiments but we have to keep it highly pressurised so it doesn’t boil away. You can do lots of fun stuff with liquid nitrogen- take a look at this:
