Inside tiny tubes, water turns solid when it should be boiling

All bets are off when you get really small

So a black hole's singularity might be infinitely hot ice?

Fantastic! I want some of those nanotube ice cubes.

Famous lecture by Richard Feynman: "There's plenty of room at the bottom." Very thought provoking and well worth the read.

No, because it’s hot. But the water is in ice state.......but not cold. It’s because the water molecules are trapped, they cannot move which is what happens when water freezes. When water is heated up the molecules become more and more energetic, and move around faster and faster. But if they cannot move, they cannot be liquid.

[BenLurkin]

Interesting.

Unanswered in the article, at least my limited knowledge is the question, if it’s frozen does that mean it’s cold? Or does the restriction in size merely raise the melting point?

Imagine a refrigerator that doesn’t use electricity. Or a cold shirt for a hot day.

(Bad pun intended) This sounds really cool!

Those amazingly clever guys/gals at MIT can do pretty much anything.

So how about developing a really good fifty-cent cigar....?

Well - if by “cool” you mean 105 degrees Celsius.

“this solid water doesn’t melt until well above the normal boiling point of water” That would have trapped water in nanotubes of a certain size as an additive at all times. When the nanotube field emission experts were trying to use the nanotube platform to build electron beam bases for displays and X-ray tubes, they would try to seal the water out. Those tiny emitters can explode unexpectedly. They went to lengths to purify and catalogue those tube types too.

“It’s because the water molecules are trapped, they cannot move which is what happens when water freezes. When water is heated up the molecules become more and more energetic, and move around faster and faster. But if they cannot move, they cannot be liquid.”

Must be a lot of pent up/stored up energy in those water molecules. Just like Kevin Bacon being stuck in church, they’re wanting to bust out and start dancing at those temps, but are trapped in the tubes. Probably lots of energetic angry vibes being sent out from being locked up like that.

They can’t move. So there is less and less energy as the nanoscale drops. That’s why the water will freeze at a higher temperature as the size goes down.

Here comes high temp superconductivity!

They only cool nanodrinks.

And you need 1,293,284,483 nanococktails to get drunk.

I would make her head explode.

Steve Martin touched upon “getting small...I mean REALLY small” in the late 70’s.

[Islander7]

They swoll up and got stuck.
