>Edit: Another hilarious question... would the water heat up? Increasing pressure rapidly in an incompressible liquid produces heating, see: refrigeration
No, refrigeration depends on the change of state liquid <--> gas of the refrigerant.
I agree a gas will become hotter when compressed. Simply because the "heat" will exist in a smaller volume.

I did way too much thinking about this today lol
It would be a super small amount of heating unless the acceleration was relativistic, so negligible
The separation effect of the acceleration (centrifuge forces) would also be pretty small at all but very high accelerations
And the amount of damage caused by the acceleration would be a lot smaller without any gas at all-- BUT gas is a byproduct of a large number of our body processes like oxygen uptake, AND that acceleration would still have a meaningful effect on your body's different systems. You would still die of a stroke at pretty small accelerations
Edit: also good call! I totally forgot about the latent heat of vaporization thing being the primary factor
