- Superfluidity is a phase of matter in which matter behaves like a fluid with zero viscosity12345. This means that the fluid can flow without any loss of kinetic energy or friction23. Superfluidity occurs at very low temperatures with certain isotopes of helium, rubidium, and lithium125. Superfluidity is related to superconductivity, which is the phenomenon of zero electrical resistance in some solids45.

This property of certain isotopes was discovered by Pyotr Leonidovich Kapitsa, John F. Allen, and Don Misener in 1937. It has been achieved at very low temperatures with at least two isotopes of helium, one isotope of rubidium, and one isotope of lithium.www.allthescience.org/what-is-a-superfluid.htmSuperfluidity is the characteristic property of a fluid with zero viscosity which therefore flows without any loss of kinetic energy. When stirred, a superfluid forms vortices that continue to rotate indefinitely. Superfluidity occurs in two isotopes of helium (helium-3 and helium-4) when they are liquefied by cooling to cryogenic temperatures.en.wikipedia.org/wiki/SuperfluidityA superfluid is a state of matter in which matter behaves like a fluid with zero viscosity. The substance, which looks like a normal liquid, flows without friction past any surface, which allows it to continue to circulate over obstructions and through pores in containers which hold it, subject only to its own inertia.en.wikipedia.org/wiki/Superfluid_helium-4Superfluid refers to the state of matter in which the matter possesses the properties of liquid with zero viscosity. There exists some connection between superconductors and superfluids. One can understand the superconductivity phenomenon as a superfluid occurring in an electrically charged system.www.vedantu.com/physics/superfluiditySuperfluidity, the frictionless flow and other exotic behaviour observed in liquid helium at temperatures near absolute zero (−273.15 °C, or −459.67 °F), and (less widely used) similar frictionless behaviour of electrons in a superconducting solid. In each case the unusual behaviour arises from quantum mechanical effects.
