What is the phenomenon of helium-3 becoming a superfluid called?
Condensation
Evaporation
Superfluid transition
Sublimation
Answer
Superfluid transition is the phenomenon where helium-3 becomes a superfluid. In this state, helium-3 loses all viscosity and flows without friction. This occurs when helium-3 is cooled to extremely low temperatures, near absolute zero (-273.15 °C or -459.67 °F). At this temperature, the atoms of helium-3 form pairs called Cooper pairs, which behave as a single entity and can flow through narrow channels without losing energy.
