Superfluuditeetti
Superfluuditeetti, also known as superfluidity, is a quantum mechanical phenomenon that occurs in certain fluids at extremely low temperatures. In this state, the fluid exhibits zero viscosity, allowing it to flow without any resistance. This behavior was first observed in liquid helium-4, which becomes superfluid below a critical temperature of approximately 2.17 kelvin (K). The discovery of superfluidity in helium-4 was made by Pyotr Kapitsa, John F. Allen, and Don Misener in the 1930s, earning Kapitsa the Nobel Prize in Physics in 1978.
Superfluidity arises due to the collective behavior of atoms or molecules in the fluid, forming a quantum
Superfluidity is not limited to helium-4; another isotope, helium-3, also exhibits superfluid behavior, though at much
