One practical property of the element
nitrogen is that it, at atmospheric pressure, boils at –320.4 F. This makes it
suitable to use in cold traps for laboratory equipment and to cool detectors
such as the X-ray detector in scanning or transmission electron microscopes.
Another, more unexpected, application of
liquid nitrogen is SUPER fast ice cream making! Liquid nitrogen has made the
ice cream café, Smitten, in San Francisco very popular.
