Yeah so, what's your point and what does it have to do with the issue under discussion, you vague nitwit.

You talked about sublimation, and how it can be explained with my theory which has it that kinetic impact causes instantaneous high temperature upon a single molecule of water, causing change of state as per the phase diagram of water. 

I explained that with the kinetic theory of gases, in an earlier post. A strong impact from an air molecule upon ice may remove a water molecule from the ice, with energy enough to raise it instantaneously above the boiling point, causing it to proceed to the vapour state from the solid state as per the phase diagram of water - and this process is known as sublimation.

You've already presented this absurd theory and ive already replied. 

Now tell us how this one hot h2o molecule and many others stay gaseous in earths atmosphere.

Does this not require more if you magical hot molecules as a regular part of ambient air?

Where does this absurdity stop?

I was referring to your point relating to sublimation.

They stay as per the kinetic theory of gases. As the water vapour is a gas it acts like any gas, no matter what some opine about this. I will allow that water vapour unlike other gases does liquefy in the 0-100degC range, provided it gets proximity to other vapour molecules. Adhesive forces come into play, then, and we get fog, mist, clouds, ice, etc.

So they remain gaseous so long as they can remain single.
I hope this is not too hard to understand.

Nothing magical about high velocity molecules you call hot molecules. That is a part of the normal distribution of molecular velocities in the gas. Given the mean velocity, one can find how much percent of the gas is hot, or cold. Just see any normal distribution, the bell-shaped curcem, brush up on statistics.

It's called "boiling."

Guess what temperature water boils at sea level?

Guess what is the temperature of the atmosphere.

What grade are you in.

Not only.  Water (like other substances) evoporates at temperatures much
lower than its boiling point.

This is why you sweat: the sweat (basically warm salty water) carries heat
from inside the body to the surface of the skin and evoporates there.
Evaporation, the ability to leave the ensemble of water molecules held
together by hydrogen bond, requires greater inner energy U for each water
molecule in the sweat; this energy is taken from other water molecules, so
that the temperature of the remaining sweat is reduced – it is cooled [first
law of thermodynamics: dU = δQ + δW = c dT + δW; cₚ(H₂O) = 4184 J/(kg K)].
Since heat always flows from the hotter to the colder substance [a
consequence of the second law of thermodynamics: dS ≥ 0], this cools the
body.  Then the evaporated molecules diffuse into the surrounding air, so
that this heat is finally transported away from the body.

You can also observe this if you have a shower or a bath or go swimming and
do not dry your body quickly afterwards.  As the water on your skin
evaporates, you will feel colder because you *actually* become colder.

> Guess what temperature water boils at sea level?

100 °C, because that is how the Celsius scale is defined.

> Guess what is the temperature of the atmosphere.

I do not have to guess, it is known: It varies from ca. −90 °C to 270 °C.

<https://en.wikipedia.org/wiki/Atmosphere_of_Earth#/media/File:Comparison_US_standard_atmosphere_1962.svg>

But that does not matter.  A glass half full with liquid water does not only
contain liquid water.

You can easily see this if you put something on top of it and wait a bit:
the bottom of the cover becomes wet because some water molecules have been
ejected or have ejected themselves from the water surface (evaporation), and
some found themselves on the bottom surface of the cover (condensation).
This process is supported by high kinetic energy of the molecules, i.e. high
temperatures.  So compare the result with that of a glass/cup of hot tea
(basically flavoured water).  Note that the tea at the bottom of the
glass/cup is still liquid; it is NOT boiling.

A higher grade than you, obviously.  I am not entirely sure, but I think
I learned evaporation and condensation in the 7th form at the latest
(several decades ago).

You cant. 

Im an expert on water.  But it shouldnt take an expert to realize you cant boil water with good intentions. 

Right?

It does.  I have already told you how to confirm this experimentally.

I have no idea what that is supposed to mean.

Evaporation is NOT boiling.  *Neither* is sublimation.  Those are
*different* phase transitions, happening only *on the surface* of substances
at much lower temperatures than the substance’s boiling point.

I have already told you how to confirm that experimentally.

And if you could read a phase diagram, not only would you realize that the
phase depends on temperature *and* pressure, but also you would realize that
there are certain combinations of temperature and pressure where a substance
exists in two phases *simultaneously*, or even all three (triple point).

You are correct up to here.

It is an ensemble that is leaving, not just one molecule.  And since liqiuid water has a huge heat capacity a lot of heat is carried away in the nanodroplet that leaves.

Most importantly--and this is something only an expert in water will understand--the ensemble that leaves still maintains hydrogen bonds with other H2O molecules in the ensemble. And since H bonds LOWER THE POLARITY OF THE MOLECULES THAT PARTICIPATE IN THE BONDS the force necessary for the nanodrolet ensemble to break away is considerably less per molecule than it would be if we were trying to remove these molecules one at a time (boiling).  Only a person (myself) who is an expert in understanding the VARIABILITY of the polarity of the H2O molecule and the fact that H bonds are the mechanism thereof is there the slightest chance of being able to explain the broad range of observed behaviors (ie. sublimation) associated with evaporation. Morons (ie. Arindam and Thomas pointy head) who stubbornly insist on standard assumptions that are ignorant of the distinctness of H2O polarity and h bonding are, well, just wasting everybodies time with your ignorant assertions. This is a subject that require and expert (myself) who has an intimate understanding of the highly variable nature of H2O polarity and h bonding.

Yes, evaporation cools. (Everybody knows this.) But this does not substantiate your simplistic model that completely breaks down when trying to explain evaporation at lower temperatures. Your model fails to explain sublimation.  My model does not fail.

Sounds like the question involves physics/science so, no, it's not off
topic. Take it from an accomplished and highly respected Ph.D.

(Learn to quote.)

Not true.  You are merely arguing from your own ignorance.

Breaking apart (hydrogen) bonds between molecules requires energy.

The first law of thermodynamics is usually written as

  dU = δQ + δW = δQ − p dV.

Since the volume of the contents of the *covered* glass of water does not
change (dV = 0), no work (W) is being done or by on the system, and any
increase in inner energy (U) that would be required to break hydrogen bonds
apart (essentially increasing the kinetic energy of the molecules so that
they would move fast enough that hydrogen bonds are not stable anymore) has
to come from heat (Q).

So if water molecules would evaporate in pairs, triplets, aso., then less
heat of the environment would be consumed by evaporation than if they
evaporated independently (which they do).  For the evaporated water, the
liquid water is part of the environment.

The (change of) heat in a system can be measured because it is proportional
to the (change in) absolute temperature (T, in K) by the equation

  δQ = m c_X dT

or IOW

             T₂
   Q = m c_X ∫  dT = m c_X (T₂ − T₁)
             T₁

with m being the mass of the specimen (in kg), and c_X being the specific
heat capacity of the substance (in J K⁻¹ kg⁻¹) where the quantity X is constant.

Since we are considering a situation where the volume is constant, that
would be the specific heat capacity at constant volume, c_V, for water.

IOW, if molecules would evaporate in pairs, triplets, then the water would
be warmer than if they would evoporate as single molecules.  This can be
calculated and measured.

I dare you to do the calculation and the measurement properly.

*You* got nothing but your armchair fantasies and  your ridiculous claim

I'm an expert on this subject.  There is no evidence of evaporation being gaseous.

Prove that the force required isn't variable and prove that H bonds don't neutralize polarity.

You are clueless.

The polarity is too high for one or few to get pushed/pulled off the surface.  

I am an expert on H bonding in water.  See my videos.

Irrelevant.  First you need to confirm your assumption that the force of H2O polarity that underlies the bonds is static (fixed) and not variable, as I have determined.

Moreover, you model fails to explain the other anomalies of water.  So, your explanation is worthless.
