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 …

As a result, some of the superfluid properties of the A and A1 phases are markedly different from those of 4 He or 3 He-B and are indeed unique among known physical systems.

Feb 9, 2022 · By definition, superfluidity is the zero viscosity flow of a fluid, such as a liquid or gas. In physics, superfluidity is a property of fluids where they have zero viscosity or are frictionless. …

The most obvious definition of superfluidity is the ability of a liquid to flow through narrow channels without apparent friction. However, this is actually only one of a number of interesting properties.

Feb 14, 2024 · Superfluid begins in the late 19th century with the race to liquify gases such as oxygen, nitrogen and hydrogen – a race that created the modern field of cryogenics.

May 21, 2024 · A superfluid is a phase of matter capable of flowing endlessly without energy loss. This property of certain isotopes was discovered by Pyotr Leonidovich Kapitsa, John F. Allen, …

May 17, 2023 · Superfluidity is a phenomenon that occurs when a fluid is cooled to extremely low temperatures, close to absolute zero (-273.15°C or -459.67°F), and it loses all its viscosity. …

Superfluidity is a state of matter where fluid or a liquid can act very strangely. Some of the things a superfluid can do are: It can flow extremely easily. (How easily a liquid can flow is called its …

Superfluid 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.

The meaning of SUPERFLUID is an unusual state of matter noted only in liquid helium cooled to near absolute zero and characterized by apparently frictionless flow (as through fine holes).
