Title: The weird science of "hot ice!"
Post by: gunug on May 16, 2007, 03:45:45 PM
I think it's great to keep on reading about scientific topics far beyond any rational "need to know" and in keeping with this I point out this interesting topic about a massive planet of "hot ice" that circles a sun that isn't our own:
Although the parent star is much cooler than the Sun, the planet orbits 13 times closer to the star than Mercury's orbit around the Sun. That means the surface must be a blazing hot 300° C or more, keeping water in its atmosphere in vapour form.
But the high pressures in the planet's interior would compress the water so much that it would stay solid even at hundreds of degrees Celsius – the expected temperatures inside the planet. There are a variety of exotic 'hot ice' states possible in such conditions, with names like 'Ice VII' and 'Ice X'. Ocean worlds!

Oh gee, and here I thought you were going to talk about the hot ice my chiropractor has me use.

Isn't that "Icy Hot?" It stinks but it's pretty effective!

You can have cold jalapenos too. Just put 'em in the frig.

There is "IcyHot", but I have hot ice gel in a bag. I can heat it, or freeze it. Works grand.

It's liquid inside?
We've got these "bean bag" things you put in the microwave...

Not a liquid, it's a gel.

Called Ultimate Cold Pack, it can be used cold (from freezer) or hot (micro or put pack in boiling water to heat). Fantastic stuff.

Oh, yeah; my Physical Terrorist used those on me last year!

LOL!
My chiropractor tells me ice, ice, ice ... that's after he's snapped and cracked my bones and I ache. But then I ached in the first place or I wouldn't have gone to see him. :=P

I used cold packs on my knee last night (see broken toe topic) and it numbed it out just fine!

The three choice were always solid, liquid, or gas - back when I was in science class.
So, what's a gel? Are there new catagories now?
I do appreciate the difference between water and shampoo, for instance, but, scientifically speaking...

From the Oxford American Dictionary:
Gel: Chemistry: a semisolid colloidal suspension of a solid dispersed in a liquid. Biochemistry: a semirigid slab or cylinder of an organic polymer used as a medium for the separation of macromolecules.
Make of that what you will.

Something else, not exactly a gel:

Researchers Create New Form of Matter
Physicists at the University of Pittsburgh have demonstrated a new form of matter that melds the characteristics of lasers with those of the world's best electrical conductors - superconductors. . . The new state is a solid filled with a collection of energy particles known as polaritons that have been trapped and slowed, explained lead investigator David Snoke, an associate professor in the physics and astronomy department in Pitt's School of Arts and Sciences. Snoke worked with Pitt graduate students Ryan Balili and Vincent Hartwell on the project.
Using specially designed optical structures with nanometer-thick layers-which allow polaritons to move freely inside the solid-Snoke and his colleagues captured the polaritons in the form of a superfluid. In superfluids and in their solid counterparts, superconductors, matter consolidates to act as a single energy wave rather than as individual particles.

I guess it's a solquid

The usual three states quoted are no longer the final matter, so to speak.
I remember explaining to one of my classes about the Bose-Einstein condensate and their homeroom teacher argued with me that there were only three states, yadda, yadda. Had to bring in some downloaded info to prove it (this was about 10 years ago).
