Superfluid Helium
You may have heard of superfluids before but let me recap by
saying that superfluids are made from elements that are gas at room temperature
and put at such a cold temperature that they become liquid. But after the point
where most elements would freeze, superfluids like helium will continue to stay
liquid. These strange superfluids seem to defy physics, although they do
technically follow the rules. They can do things like flowing through molecule
thin cracks and climbing the walls of their container. Basically the fluid,
rather than combining into a solid and staying still, will continue to have
some movement no matter how cold they get. They will however be moving little
enough to move through molecule thin cracks in their container. Helium becomes
a superfluid at around 2-3 kelvin.
What are some ways that superfluids could actually help?
What other elements besides helium can become superfluids?
Is there any other thing that could happen at extremely low
temperatures?
I think that maybe we could make other gases like hydrogen into super fluids and find uses for those as well.
ReplyDeleteIs it expensive to create super fluids?
ReplyDeleteIf you have the elements you need and the machine you need then its actually very cheap.
DeleteI don't see any particular practical use for superfluids besides the study of them
ReplyDeleteI don't think there is any real use for this.
ReplyDeleteWhat about the structure of the superfluids allows them to stay liquid at such cold temperatures?

The atoms of helium in gas form are moving so fast that even when they are cooled and lose that energy they are still moving so fast that they never settle into solid form.
DeleteSame I agree with Hannah Z above just because we have way more things to focus on and I dont see any use for this other than a waste of time and how its a little cool.
