Co2

Ever wonder what happens if you dump 25kg of
dry ice into a swimming pool to cool it down?

The Moscow party-goers found out.
Three suffocated.

Well did the pool cool down at least?

LoL

I can't imagine that even that amount would have had
much effect on a swimming pool!
Perhaps one of the physicists here can do the calculation?

29!
One of the few times in my life when I celebrate my birthday!
Thanks to everyone who
has already congratulated😘 I can
not answer everyone - but just know, I am very pleased))) And who is not, I expect congratulations in the form of 💖💖💖

Nice looking gal. Shame

A proper Russian should have been studying chess 🤔

She succeeded. Three people never need pharmaceuticals anymore.

should be renamed Co3.....Choked only three

Pity they didn’t have a friend like Ponderable there.
Talk about a freak accident!

Indeed. He'd likely have come up with the right amount to accomplish the mission. Oh, and he'd probably said, "Don't put that in until I'm a few kilometers away. I'll call ya when I'm there." 😲

So now I have read the thread...

We are talking about 25 kg of CO2, that is about 569 moles or at room conditions or 12,5 m3.

A concentration of 8% in air is enough to kill a person. So this 12,5 m3 woud suffice to poison 100 m3 of air....
We can assume that the Co2-concentration directly above the water is much more affected than in the whole room....

On the cooling: dry ice has a sublimation enthalpie of 25 kJ/mol, so the 25 kg have a heat of 14,2 MJ with a heat capacity of 37 J/mol*K we get another 2.1 MJ so we have 16.3 MJ cooling power. Witha heat capacity of water of 4,2 KJ/kg*K we can vool 3,88 m3 water for ONE Kelvin. That would be a cube of 1,57 m length or a rather small swimming pool.


In short words: The chemist would have strongly recommended to use cold water to cool down the pool....

@Ponderable

Thank you, I’ve copy and pasted your analysis to show my ex husband. He’ll appreciate that as we were talking about it earlier.

You actually sound like a chemist! 😉

Are you swearing?
