Super Fluid
SUPER FLUID S uper fluid was originally discovered in liquid helium,by PYOTR KAPITSA & JOHN F.ALLEN. The theory of superfluidity was developed by Lev Landau. Super-fluidity occurs in two isotopes of Helium [Helium-3 & Helium-4] when they are liquified by cooling to cryogenic temperatures i.e, T=-269℃ or 4.15K . When cooled further 2.17K or -271 ℃ called its Lambda point,a remarkable thing occurs ,the liquid density drops, and the liquid becomes a zero viscosity"SUPER-FLUID" The characteristics of superfluid S uperfluid has some weird characters that doesn't happen in real time, I mean in our day to day life . T his weird character of a liquid can't be explained by our normal physics and classical laws. It can be explained clearly by a renowned model/law called QUANTUM MECHANICS . J ohn S aunders explains how a fluid can flow without friction...He explains the reason behind the weird behavior of super fluid . A nd one more thing is ...
