It would do both. Some of the water would flash boil, which would suck the heat out of everything around it, causing the rest of the water to freeze. Once the boiling stops you'd be left with a bunch of ice which would slowly sublimate away.

The pregnant patient was extremely lucky to survive: >In this case it was obvious that the abdominal implantation was secondary to undiagnosed ruptured left tubal ectopic pregnancy.
The patient needed an emergency c-section and a blood transfusion.
>In our opinion, bleeding from placental implantation site is the most life-threatening complication during laparotomy.
Extremely lucky to have survived.

Reply to comment by [deleted] in TIL that Chinese Food was introduced into America during the California Gold Rush, starting in 1848. As 30,000 immigrants had arrived from the Canton region of China, the restaurants gave the predominantly male population a connection to home and provided gathering places for the Chinese community. by jdward01

I know this isn’t what the post is about, but that chart is absolutely idiotic. It’s like ten different measurement systems with totally different use cases, no connection to each other, and zero reason to ever convert between them, mashed together without rhyme or reason and arranged in a way that seems deliberately haphazard to make them look more confusing:
-
Twips, points, picas, lines, and sticks are typesetting measurements, and never used outside of that context.
-
Nails, spans, ells, skeins, and spindles are units of measure specifically for fabric, and never used outside of that context.
-
Ropes, rods/poles, Gunter’s chains, and Ramsden chains were units for surveying, named after actual tools, and never used outside of that context. They have no real relation to each other aside from through feet, and generally weren’t ever converted from one to the other.
-
Fathoms, shackles, cables, and nautical miles are all nautical units of measure, and never used outside of that context. Fathoms are also a unit of depth, and as such not generally used to measure distance.
-
Hands, digits, palms, fingers, shaftments, paces, and grades/steps were mostly colloquial units of measure used before measuring implements were widely available.
-
Furlongs are mostly anachronistic, and were only ever really used to measure horse races.
-
Poppyseeds and barleycorns are units defined by a standard set in the 1300s and haven’t been used in any capacity for hundreds of years.
-
A Roman mile is a literal ancient Roman unit, and has nothing to do with the rest of this chart.
Just because all these units were somewhere, at some point, used by some number of English-speakers for some purpose, doesn’t mean they’re all part of the same system of measurement.

They need a chart like that for volume conversion as well.

I think they might have added something like this since then actually, as a sort of DIY solution in case this happens again!
I think it's literally a straw tube sort of thing too, haha. But I could be wrong! :3

Probably not the walrus kind, but they do have human protheses:

> Vacuum kills pretty quick.
No, it doesn't. The overwhelming majority of instant death scenarios would be collapsing of the lungs. If not, you have consciousness for about 15 seconds since your bloodstream still has oxygen in it which we have evidence of, not to mention rough calculations of oxygen saturation in the blood.
If you still have your lungs though, it's estimated that you can survive in space for about 2 minutes without permanent damage (ie significant loss in function).
Though, with regards to brain damage - generally you can survive 5-10 minutes deprived of oxygen without significant loss of brain function. The upper limit of avoiding brain death from oxygen deprivation is around 20 minutes.
However the dangerous bit here is primarily that you'd be on a spacewalk, meaning it would be near impossible to retrieve you in time. Not only does putting on a spacesuit take a significant amount of time, but they operate at a far lower atmospheric pressure than the space station, so they'd be fighting severe decompression sickness at the same time. It's hard to say though, because I don't know if they have any sort of procedure for that type of thing.

The vacuum isn't cold, but the water trying to boil away in the low pressure would suck the heat out of anything it touched (since boiling takes energy), including the remainder of the water, which would cause it to freeze.
