Why does helium behave strangely at super cold temperatures?
Imagine you're chilling with friends, and someone spills a glass of helium in liquid form. You'd expect it to behave like any other liquid, right?
But at super cold temperatures, helium doesn't flow like water. Instead, it enters a unique state where it can move without friction, defying normal liquid behavior. This strange state is called superfluidity.
Example
If you tried to stir the helium, it would glide smoothly without any resistance, unlike water.
Remember this
Superfluidity in helium-4 is a macroscopic quantum phenomenon that occurs at extremely low temperatures.
