1. a fluid that flows without friction or viscosity at very low temperatures
Usage: physics

1. having the properties of a superfluid; flowing without friction or viscosity
Usage: physics

Examples

• Liquid helium becomes a superfluid when cooled below 2.17 Kelvin.
• The superfluid can flow through tiny openings without any resistance.
• Scientists study superfluid helium to understand quantum mechanics.
• The superfluid state exhibits zero viscosity and infinite thermal conductivity.
• Researchers observed superfluid behavior in the laboratory experiment.
• The superfluid properties disappear when the temperature rises above the critical point.
