liquid helium
Coldest common refrigerant
Liquid helium is helium cooled to extremely low temperatures, below -269°C (-452°F), where it becomes a liquid.
It serves as a coolant for superconducting magnets in MRI machines, particle accelerators, and research equipment.
Below about 2 Kelvin, helium becomes a superfluid with bizarre properties—zero viscosity, the ability to climb container walls, and flow through microscopic openings.
