[–] Corno@lemm.ee 263 points 2 years ago (4 children) 30°C is 303 Kelvin. Half of that is 151 Kelvin, which translates into a fairly mild -122°C!

Lb-mole? That one I'm not sure. To me, these wanna-be scientific units are weird, like, just use metric at that point 😅 Also 1000th of an inch. Like, come on! You're just teasing us permalink fedilink source parent [–] ornery_chemist@mander.xyz 46 points 2 years ago (4 children) New strategy to prevent global warming: just freeze all of the CO2 out of the air! permalink fedilink source parent hideshow 8 child comments replies: [–] Hupf@feddit.org 8 points 2 years ago I'm dreaming of a white Christmas permalink fedilink source parent [–] mipadaitu@lemmy.world 6 points 2 years ago (2 children) That's one of the ways proposed for terraforming Venus. Put in a sun shield to freeze the planet, let the CO2 snow down, then process the CO2 into something that can sequester it away so it doesn't just go back into the atmosphere after removing the sun shield. Of course none of that is technically possible right now, but it's a lot easier on a planet that has no (known) life to destroy while working through the process. permalink fedilink source parent hideshow 4 child comments replies: [–] isolatedscotch@discuss.tchncs.de 3 points 2 years ago the sequestering step is actually kinda easy, it's the sun shield that's the hard part permalink fedilink source parent [–] xenoclast@lemmy.world 2 points 2 years ago That sounds great. I bet it would be even easier to do on earth. If anyone gave a shit. permalink fedilink source parent [–] noxy@yiffit.net 5 points 2 years ago mmm, delicious carbonjack permalink fedilink source parent [–] unrelatedkeg@lemmy.sdf.org 3 points 2 years ago Dry snow doesn't sound like too bad of a proposition on its own. permalink fedilink source parent [–] Eiri@lemmy.ca 8 points 2 years ago (2 children) Wait, does it? Are joules in thermal energy per kelvin a purely linear relationship? permalink fedilink source parent hideshow 4 child comments replies: [–] Verat@sh.itjust.works 12 points 2 years ago* (1 child) For the most part, it varies by material and state of matter, but assuming the chemical composition doesnt change and no material changes phase, then it is pretty close to linear in most materials. permalink fedilink source parent hideshow 2 child comments replies: [–] PmMeFrogMemes@lemmy.world 4 points 2 years ago hmm but there will surely be a lot of phase changes with a drop in energy so substantial. we need our top scientists on this asap permalink fedilink source parent [–] TonyTonyChopper@mander.xyz 7 points 2 years ago* (last edited 2 years ago) Fun fact: gas pressure changes linearly with temperature. If you make one of these plots at mild conditions you can extrapolate the line down to zero pressure and measure where absolute zero temperature is permalink fedilink source parent [–] Phoenicianpirate@lemm.ee 1 point 2 years ago 😱 permalink fedilink source parent
