Help understanding chemistry (an idea for harnessing energy)

[andrewbb]

Two theories on water evaporation:
1. water molecule turns in such a way that two oxygens create a magnetic repulsion and the water molecule is pushed into the air.
2. water molecule turns in such a way that its magnetic attraction to something in the air (eg. nitrogen) is greater than the hydrogen bond that causes water's cohesion. That pulls it into the air and it floats upward.

In the case of boiling, I think water vapor is stand-alone and does not adhere to other molecules/atoms immediately. However, in the case of evaporation, I think water molecules adhere to molecules/atoms in the air such as nitrogen. Saturation of the surrounding air means all the nitrogen has a water molecule adhered to it. Probably a bit of both is going on.

My point in saying this is that evaporation does not require heat or sunlight to be added. It occurs at the molecular electromagnetic attraction/repulsion level.

I don't know where he got that equation from, but you can see easily enough from heating water on your stove or setting a glass of water on your driveway that it doesn't even boil that fast, much less evaporate that fast. That only takes a very small amount of critical thinking skill to recognize.

Further down on "the van"s page, someone asks the source of the equation and "the van" doesn't look it up. I think "the van" remembered the equation incorrectly and should have realized the answer was nonsense.

Water does evaporate without heat added.

Googling comes up with this equation and example for water evaporation from a pool: http://www.engineeringtoolbox.com/evaporation-water-surface-d_690.html

No it doesn't. The heat required to boil a cup of water and to lelt it evaporate naturally is exactly the same.

My thinking is that in a closed system, saturation of the surrounding air is the goal.

If the air is saturated, water can no longer evaporate: that's what "saturation" means: the air his holding as much water as it can.

Two theories on water evaporation:

You don't need to idly speculate your way into this, you need to open a chemistry or thermodynamics book and learn the reality of how these things work. And we won't humor idle speculation here.

You need to take a step back/deep breath and start thinking critically and learning properly. Idle speculation based on complete ignorance of a subject (any subject) is not a path to learning/discovery.

Boiling is DIFFERENT than evaporation. Boiling does take energy and vaporizes water quickly.

However, evaporation exists. Same temperature. I'm not sure why you're getting emotional about a physical process, but evaporation happens.

So, how does it occur? Well... cohesiveness of water would be the thing to look at. That's determined by the hydrogen bond of hydrogen atoms on that water molecule. How does a water molecule separate from that bond? Well... somehow it is being either repelled or attracted to something else. I've described the process above.

In a system of water & air that is of the same temperature, does evaporation exist?
Answer is of course yes.

Therefore, something is happening at the molecular level that does not require "excitetation" or heat added to the system.

I've described that process above. Sorry, but your textbooks were incomplete.

What I've described above is the NEW science that replaces chemistry and is called Molecular Dynamics.

Chemistry is dead?

This is sweet, now I don't have to worry about passing that AP Chemistry exam!

Your understanding of how evaporation works is incorrect...your understanding of why is even worse.

FYI, I make my living designing heating and air conditioning systems, including evaporative cooling systems such as cooling towers. Cooling towers cool water down below ambient temperature by evaporating some of the water to carry off heat. (Your sweaty skin does the same thing on a hot day, by the way). So as a last-ditch effort (that I won't back-check to see if it worked...), please read the wiki on wet bulb temperature, which is a way to measure heat loss due to evaporation: http://en.wikipedia.org/wiki/Wet-bulb_temperature

Sorry, but as I already said, this is a site for discussing real science only. What you are saying is crackpottery and it is not worth our effort to try to turn you back toward reality. You must choose to do that on your own. If you make that choice, then we can help you make the trip.
