Definition

A type of fluid that can flow without any resistance, usually found in liquid helium at very low temperatures.

Example

Liquid helium becomes a superfluid when cooled to near absolute zero, allowing it to flow without friction.

Conversation

Have you ever heard about superfluid helium?

Yeah, I read that it flows without any friction at super low temperatures.

Exactly! It's such a fascinating state of matter.

I know, right? It sounds almost magical how it behaves!

Root Explanation

Superfluid → It is formed from "super-" (meaning above or beyond) and "fluid" (from Latin "fluere", meaning to flow). The word "superfluid" describes a state of matter that flows without viscosity, going beyond normal fluid behavior.

Memory Tip

Think of something that flows 'beyond' ('super-') the usual limits of fluidity — that's what superfluid means.
