I remember there being something misleading about the "temperature" in pV=nRT, but yeah, I think I was getting confused because I was thinking about it purely formulaicly.
But if the pressure drops and the volume of the gas increases, in order for it to cool, that would mean the drop in pressure is much less significant than the rise in volume?
But yeah, I should've remembered that expanding gasses cool, because I know how aerosol cans work. It's time to touch up on this stuff lol.
If this happened near or post-interplanetary colonization, I'm reasonably confident that they'd be named after or by whichever corporation buys and takes the largest influence over the planet.
We all know Elon wants to name Mars Planet X, so let's agree now to blow it up as soon as that happens.
Earth's name would probably be left alone. I'd imagine Google going after Saturn and maybe preserving the name too, maybe giving it a little name if they hadn't blown every word in the English language on dead projects.
Microsoft, in their lack of vision, would name Mercury Microsoft (if they're still around by this point).
