aaah crap nerdsniped by lighter than air

what if instead of a hot air balloon you had a way hotter air balloon
Prikaži ovu nit -
since more energetic molecules press more against the skin of the balloon you could get more lift

like you could have STEAM BALLOONS i mean just THINK OF IT we could enter the STEAM PUNK ERA LIKE FOR REALSIES
Prikaži ovu nit -
of course there'd probably be a problem that the steam would cool down a lot so it'd have to be insulated?
Prikaži ovu nit -
okay next idea what if instead of steam we used argon
Prikaži ovu nit -
as a noble gas all its kinetic energy would be in the form of velocity rather than the spinning you get in molecules. 1 degree of freedom == more energy dense?
Prikaži ovu nit -
of course argon's denser than air, but we just make it hot
Prikaži ovu nit -
helium: leaks, expensive. hydrogen: leaks, very dangerous
Prikaži ovu nit -
I guess worst case maybe the gas bag starts leaking argon into the cabin and you asphyxiate but I'm not sure how real of a risk that would be

physics book sez "the average translational kinetic energy per molecule depends on on the temperature, not the pressure, volume, or kind of molecule"
