Actually PV = nRT is just an equation of state for an ideal gas that

If there are any meaningful definitions of "chemistry", "thermodynamics",
and "physics" anymore, then PV = nRT belongs in the second, which is a
branch of the third. But this is a philosophical quarrel that we'll not
solve here.

All I know is, there ain't no oil in my raw shop air, hot as it may be.
And certainly not compared to proximity to my 2-stroke outboard, 2-stroke
chain saw, 2-stroke string trimmer, or 2-stroke Weber charcoal grill.

Hey, if we adapt this train of thought we can do away with diving related
illnesses like nitrogen narcosis and embolism! Oh, happy day!
Could it be that the rings in your compressor aren't shot? Breathe the
exhaust of any of the other items you list at depth and under pressure and
let me know what you find out.

You're in full definitional retreat. We're talking about using a sound
compressor to dive just below the surface to work on a boat hull. Not a
busted compressor and plumbing the abyss.

This thread is getting dumber and dumber.
Neither nitrogen narcosis nor embolism
have _anything_ to do with breathing oil fumes
or other garbage.

Everybody go back and study physics 101 and biology 101.
If that seems confusing, borrow highschool textbooks
from your teenage children. Do not post before finished.

Good night.
