And I presume the OP is aware people can survive snowy days 
Slightly tangential, but still implying you’d have a couple of seconds: If you were thrown into the vacuum of space with no space suit, would you explode? - The Straight Dope
It’s certainly possible to imagine something approaching 0 Kelvin. But I don’t see any justification for saying
Perhaps.
At 0 K, the average kinetic energy of the atom is obviously zero. But if KE = 0, does that mean the *total *energy of the atom is zero? I don’t know.
More succinctly put:
- You can’t win
- You can’t break even
- You can’t get out of the game
No.
Cause entropy will take it all, though it may seem a shame. That, in a nutshell, is what entropy’s about. You’re now down with the discount.
Who’s down with entropy?
The atom still has mass. E = MC^2, right? Being at 0 Kelvin means the atom is in its ground state, but not that it has no energy.
The OP didn’t ask how long you’d take to freeze, but how long you’d survive. Given that Oxygen would be in an unbreathable form at that temperature I don’t think the cold would kill you, you’d die of shock, suffocation or some other cause first.
I was wondering about that. Of course, at 0 K you’d just suffocate because air would be solid and you couldn’t breathe, period.
But even assuming an Earth-like environment with a temperature juuuust above the condensation point of oxygen, wouldn’t the frigid gas breathed in cause extensive lung damage through frostbite, quickly followed by drowning in one’s own blood ?
I like it.
Yeah, you know me.
This thread reminds me of the excellent NOVA program: Absolute Zero.
A cool look at the quest to reach Absolute Zero. SPOILER: haven’t done it yet!
Oh, that would be me.

I suppose if I take my glove off on the Moon in a shadow. It won’t freeze quickly because of the lack of conduction and convection. Now suppose I use my bare hand to scoop up some moon dirt. What would happen?
Just like the liquid He vs vacuum mentioned above, your hand would freeze a lot faster.
Right. And it would depend whether it was night or day on the moon! The surface gets hot during the day (it can stay somewhat warm in a shadow)! At night, it gets well below the temperature of your basic dry ice you can buy at the store. If you grab dry ice with your bare hands (note: don’t ever) and hold on tight it’s cold enough to cause very serious tissue damage fairly quickly.
I think so but that is still at a temp above Zero K.
Thanks, didn’t know that. I admit I hadn’t considered vacuum energy but that manages to exist in space where the temp is still above Zero K. Still, we live and learn - that’s why I joined this board. 
Always happy to recognise mistakes.
