Welcome
We're not The Onion! Not affiliated with them in any way! Not operated by them in any way! All the news here is real!
The Rules
Posts must be:
- Links to news stories from...
- ...credible sources, with...
- ...their original headlines, that...
- ...would make people who see the headline think, “That has got to be a story from The Onion, America’s Finest News Source.”
Comments must abide by the server rules for Lemmy.world and generally abstain from trollish, bigoted, or otherwise disruptive behavior that makes this community less fun for everyone.
And that’s basically it!

MODERATORS
The rapidly expanding co2 does get very cold though. It’s not any different from freezing things with compressed air cans.
I don’t hover, know which would absorb more heat per pound though. Someone who knows more math than I can do it though.
If I’m reading Wikipedia correctly, it takes 348 Joules of heat to boil a gram of CO2.
Water is 2257 Joules per gram. As long as you don’t need anything cooled under 100C, water is the way to go for cooling. It’s also a hell of a lot cheaper and easier to deal with than liquid CO2.
