We’ve all probably seen liquid nitrogen in action (think the banana in the liquid nitrogen and when they take it out and are able to smash it to pieces). Liquid nitrogen comes in third, and boils at a temperature of 77 Kelvin (-195.79 degrees Farenheit). Liquid oxygen is used extensively in the space program as a propellant and also in the medical field. It’s also a strong oxidizer, which means organic material will burn rapidly in liquid oxygen. Its freezing point is 54.36 Kelvin (-361.82 degrees Farenheit) and causes anything it touches to become very brittle. Liquid oxygen is also extremely cold, although not near the levels of liquid helium. and the world and comes about as a byproduct of natural gas production. The panhandle of Texas is the prime helium production point in the U.S. Federal Helium Reserve near Amarillo, Texas. produces 75% of the world’s helium and 30% of that is held in the U.S. Liquid helium is used in superconducting magnets such as MRI machines, silicon wafer production, arc welding, and cryogenics. In this strange form, liquid helium can appear to self-propel itself and defy the forces of gravity and surface tension. A superfluid is matter that behaves like a fluid with zero viscosity. When helium is cooled to a level of 4 Kelvin (-452.2 degrees Farenheit) it takes on a liquid form and when cooled further to 2.17 Kelvin (really cold) it behaves like a superfluid. They’re getting a paused picture of the mechanics of a molecule with the possibility of discovering some new, exotic form of matter. The scientists here are doing essentially the same thing. There are all sorts of things you can pick out and discover that would have flown right by at normal speeds.

Think of it like hitting pause on a movie to examine the scene. The reason for all this cooling of molecules allows scientists to see what quantum mechanics are at play that would never be seen under normal temperatures and conditions.

The result was a molecule that lasted only 2.5 seconds long, but in the world of physics, that is a tremendous amount of time.

Sodium and potassium don’t form a molecular bond at normal temperatures since they are both positively charged, so bringing them together using the magnetic field under the cold conditions allowed them to see a new, complex molecule that would never form on its own. While the team at MIT used lasers to cool the molecules, they had to use a magnetic field to bring them together. It’s not possible to get colder than absolute zero. Absolute zero is where nothing can be colder, and there is absolutely no heat left in a substance (that is -459.67 degrees Fahrenheit, or -273.15 degrees Celsius). That’s only 500-billionths of a degree above absolute zero. The temperature got to as low as 500 nanokelvins. It was the first time anything chemically bound had been ever made this cold. The scientists pulled it off by taking away the heat of the individual gas molecules of the sodium potassium gas using lasers.

The reason for cooling molecules to such mind boggling temperatures helps scientists understand the physics that occur at such extreme temperatures, and what atoms do when they get very, very cold.
