In physics the forth state of matter is called plasma.Good luck.
Well then its five states isn't it. What do you call the visible evaporation of water before the boiling point,
taint water? It taint this and it taint that? Perhaps we should pretend it doesn't exist. It could be its just a figment
of my imagination.

There are only four states. What you see is an aerosol.

It looks like 12 to me.

Edit;the definition of vapour
1.
a visible exhalation, as fog, mist, steam, smoke, or noxious gas,diffused through or suspended in the air:
the vapors rising from the bogs.
2.
Physics. a gas at a temperature below its critical temperature.

How does water evaporate if it doesn't boil?

BTW - steam is completely transparent. If you can see it then it is water vapour. Consider a kettle boiling - the white plume only occurs a short distance above the spout. Below that it is steam, above it has cooled into vapour.

There are only 4 states. The other 8 are processes, not states. Much earlier in this thread, I pointed out the distinction between how the term "vapor" is used in common parlance, which is the first definition you cite, and the second definition, which is the correct scientific definition. HERE is a link to a page from the Purdue chemistry department which correctly uses the term "water vapor" to describe the gaseous state of water and goes on to explain the meaning of "critical temperature," which for water is 374 deg. C, 705 deg. F.

You must be trolling. I think you've been doing it all along, so this will be my last post on the subject.

I am not trolling. One cannot discount transitional phases in discussing a subject. To fill you in
a little me and Traveller have had an ongoing discussion on how e-cigarettes work. Vapor or
more correctly visible water vapour will start forming at about 184 to 186 F when water is heated
for the specific purpose of obtaining said vapor. Optimum water vapor is produced at around 196 F.
Certain things will have an effect on the transitional stage most notably height above sea level
and in extreme cases barometric pressure. This is important to know because e-cigarettes rely on this
water vapour to atomize the base mix (PG/VG) and the ingredients dispersed and suspended in
it to be atomized into an aerosol. This how your basic cigalike works. Thru the years people by
using larger batteries and lowering the resistance of the coils thus increasing the amperage which
increased the amount of heat applied and vapor produced. There is a quasi linear logarithmic
equation involved which I don't understand. This evolved into sub ohm mods, V V and V W and now
the now the high wattage regulated mods today.( not necessarily in that order) My point is all
these devices are based on the same basic principals.
Note there are different ways to look at critical temperatures of gas.
Critical Temperature and Critical Pressure

The obvious way to turn a gas into a liquid is to cool it to a temperature below its boiling point. There is another way of condensing a gas to form a liquid, however, which involves raising the pressure on the gas.

When I saw this thread I was hoping to learn about what happens when vaping from the community's combined experience and find out just how inaccurate the studies were. (Thought maybe a different element coil would reduce the production of free radicals.) instead I find a bunch of posts arguing over what an aerosol technically is. I joined this forum to learn more about vaping, not to listen to people arguing over things that don't even matter. Can someone redirect me to where this study is discussed by a "community"?

If you are interested in the study and understanding what it means it doesn't hurt
to understand how the products you are using operate. Then again I kinda get your point.
