Definition

The ability of a liquid to flow without any resistance, occurring at very low temperatures, particularly in liquid helium.

Example

At temperatures close to absolute zero, helium exhibits superfluidity, allowing it to flow without friction.

Conversation

Have you heard about the concept of superfluidity?

Yeah, it's fascinating how some liquids can flow without any resistance.

I read that it happens at really low temperatures, like near absolute zero.

Exactly! Liquid helium is a great example of superfluidity in action.

Synonyms & Antonyms

Root Explanation

Superfluidity → It is formed from "super-" (meaning above or beyond) and "fluidus" (from Latin, meaning fluid). The term describes a state of matter that behaves like a fluid with zero viscosity, allowing it to flow without resistance, thus going beyond normal fluid behavior.

Memory Tip

Think of 'super-' meaning 'beyond' and 'fluid' referring to a liquid — superfluidity is a state of liquid that flows without any resistance, going beyond what we expect from normal fluids.
