تعريف superfluidity في الإنجليزية الإنجليزية القاموس.

The frictionless flow of a liquid at temperatures near absolute zero, especially that of liquid helium

The frictionless flow of a liquid at temperatures near absolute zero; especially that of liquid helium

Unusual property of liquid helium cooled below -455. 75 °F (-270.97 °C). At such low temperatures, helium exhibits an enormous rise in heat conductivity and rapid flow through capillaries or over the rim of its container. To explain such behaviour, the substance is described in terms of a "two-fluid" mixture model consisting of normal helium and superfluid helium. In normal helium the atoms are in excited states (see excitation), whereas in superfluid helium they are in their ground state. As the temperature is lowered below -455.75 °F, more of the helium becomes superfluid. It is assumed that the superfluid component can move through the container without friction, thereby explaining the unusual behaviour
