your over complicating the process.
the VG and or PG never gets that hot.
Bases
Flavours and nicotine are dissolved in hygroscopic (absorbs water from the air) components, which turn the water in the solution into a smoke-like vapour when heated. Commonly used hygroscopic components include propylene glycol, vegetable glycerine, andpolyethylene glycol 400 (often sold under the abbreviations PG, VG, and PEG 400, respectively).

Then why do most TC vapers set the coil temp above 420*F?

as the amount of heat applied goes up the amount of vapor
produced accelerates. more vapor in less time.
before VV and VW and now the newest wiz bang stuff
lowering the resistance of the coil or increasing voltage
was the only way to increase the heat. then when VG
was introduced as a few people are allergic to PG it
was discovered that the VG makes the vapor appear thicker.
after that it was off to the races.well actually VG is thicker
than PG hence the vapor is thicker.what i mean by vapor
is we call it vapor.that's ok.
they don't call coil and wick assembly's atomizers for nothing.

It's all vaporizing, not just the trace amounts of water. Those pressure sprayers for water or bug juice produce a mist, not at all like what we emit when using electronic cigarettes. Same as with inhalers. Discharge one onto a paper towel. It will leave a wet spot if you spray enough. Blow e-cig vapor onto a towel. There won't be any wetness unless you are spitting...

no the water is vaporizing,the PG and or VG are atomizing.

I don't think it is possible for 1 part of a solution to vaporize while the others atomize when heat is applied. The solution has different vaporization temps than its individual parts. Perhaps we don't vape with enough heat for the e-juice to completely vaporize, but enough that visible 'vapor' is emitted...

that's my whole point.
its the water that's vaporizing.
its the PG and VG that add opaqueness and hold the
ingredients together.

No that is your Delusion.

The water is not Making anything.
The water is also Vaporizing, however it is Diminishing the overall Dense Vapor Diluting it as needed.

Again, PG replaces water in accomplishing the same thing while being a more Vape friendly Medium.

You simply refuse to pay attention :facepalm:
Hydroscopec is a dual action process and those solutions will also release H2O at room temps in a drier environment.
Your argument does not hold Water :lol::lol::lol:

This is why I allow any solution removed from my refrigerator or freezer to reach Room temp before breaking the seal.
Also why I never Mix while cooking is going on in the kitchen - Steam increasing humidity.

delusional?that's rather harsh.
I have taken time to read every post and link
in this thread. perhaps you missed my post

that is why some cigalike makers add up to 20% water.
water enhances the vapor. it increases vapor production.
of course to much water will have the opposite effect.
it depend on the blend.

I did, and found your assertion pointless and incorrect. You are assuming a Hydroscopic mixture is absorbing rather than expelling or neutral to relative humidity.
That is what we call single side science simply to prove ones personal assertion over Established facts.

Personally I have better things to do.

that's because the average relative humidity in the
USA is 30% which would give PG about 8.xxx to
9.xxx% water content when the temperature is
between 60 to 80 F.

ps. I suppose you found the link I provided in [HASHTAG]#218[/HASHTAG]
pointless and incorrect.
