Superfluidity is a quantum-mechanical phenomenon occurring in certain fluids, typically at very low temperatures, where the fluid exhibits frictionless flow and other unusual properties. This state was first observed in liquid helium-4 below a critical temperature of 2.17 Kelvin. Superfluidity is characterized by the absence of viscosity, allowing the fluid to flow without any loss of kinetic energy.
In a superfluid, the fluid can flow through narrow channels without any resistance, a property known as
Superfluidity is a manifestation of quantum mechanics, where particles in the fluid form a coherent state,
