I'm beginning to think the Sci-Fi documentaries on Sony Movies were wrong. I actually watched one the other day where a hole in the ozone layer caused really cold air to appear and instantly freeze people solid.
Sounds like Artic Blast with Bruce Davison & Michael Shanks, a 2010 movie rather than a documentary.

Yup, that didn't go well at all.....
Another SN failure, ending with a Kaboom.

Since humans are composed primarily of water, and so is lake Utah, one cannot freeze the other. If the lake was cold enough to do that, it would have been solid ice so he couldn't have "fallen into it".

Where logic meets physics. Try the First Law. Also observe the freezing point changes with dissolved salts. Include the temperature of air and the dew point. Things are never as simple as you wish.

If you've already watched that, be worried that you're more like me than you want to be.
Nope.
If you googled it, you're a bloody cheat.
Nope
Computer/Films(J)/Artic Blast (2010).
Along with several thousands more of all genres.
As for the film itself, not too bad, but in my opinion, could've got a better actress to play his daughter.

I don't have to look anything up to know that something at 0C cannot cool something at 37C down to 0C for a very long time, and it will never cool it to below 0C unless there's evaporation. So, no instant freezing.


However water with dissolved salts in it can be liquid below 0C and so freeze something else.

Oh dear, you are so, so so lacking in the basics of how refrigeration works. I could freeze you into a solid block of ice using water at 4C in an airflow of about 10m/s. Given enough water, or a higher air speed it might take a minute or so. (This is how some meat chilling systems work)

Obviously never made ice cream or seen why roads are salted.

This is starting to become a bit of a rant.
Perhaps it's time to end it.

This just comtinues a long established trend.

I was watching a video about "The Secret of Synchronization" last night and in it they show how ice forms. Watch it from https://youtu.be/t-_VPRCtiUg?t=549, although watching the whole thing is really interesting. As are all videos of Veritasium. Anyway, ice forms not gradually, but goes from water, water, water changing to ice almost instantly.

What air is flowing inside a lake?
People and ice float. Then again if he hit play he might have more information ...

So 95% of him was in 0C water. That won't freeze him. 5% of him (not a lot) is damp and exposed to very cold air, too cold to cause evaporation. Where exactly is all that body heat moving to?
Then again if hit play he might have more information.
