Nitrox With A Drysuit?

I beg to differ. Second law of thermodynamics. It just takes time since diffusion is slow.

And they won't ever separate since two separate phases/layers of miscible components is a state of lower entropy. You can't go that way without paying some energy. Second law again. Does your whisky separate in a 96% layer on the top and a water layer at the bottom? If it does, make sure to publish because that'll be a scientific breakthrough and may form the basis for a perpetuum mobile.

You are absolutely right about unmixing them. But diffusion can be really, really slow. Mustard gas in WW I would stay lingering in the trenches for days. The addition of high energy farticles will certainly cause a much more rapid mixing of gases.

Is argon super cheap or is that reason just a way to slightly extend dive time? Maybe I'm doing it wrong but I don't usually put all that much gas into my drysuit.

It may depend on the dry suit. neo vs a shell suit.

Main reason lakes have thermoclines is water is heaviest at about 40 deg F

Places like the Black Sea are hypoxic because of the lack of circulation.

Granted, a dry suit is going to have a lot more circulation and mixing than a lake. If you think about it, a dry suit at that kept a diver neutral at the surface filled with air and then goes down to 130' and has argon added to keep the diver neutral is going to be 80% argon.

There is a big difference between gases mixing and liquids mixing.
