What would you like to do?
water vapor is actually the separating of molecules between one another. so as water evaporates, it is releasing individual molecules
It's called sublimation.
Becomes a gas (i.e. water vapor)
The only difference between the molecules of any substance in different phases is their speed; they remain exactly the same in all other respects, otherwise they cease to be t…he same molecules and therefore are a different substance.
First of all, I have to assume that by "vapor" you mean gas. Water gas is steam. Second, you have to realize that the only difference between water as a gas, and water as a li…quid, is the energy in the molecule. We measure that by measuring temperature. Temperature is a direct measurement of thermal (heat) energy. (I know some techie is going to jump on that word, "direct" ... anyway) Think of a running car engine (with no key). When it is on, it is vibrating, making noise, maybe even moving fast. It does that until all the energy (gas) is gone, then it stops and is still. It's the same engine, just at rest. If you add more gas/energy, and give it a spark, vroom and it's back in motion. Just like that, a gas water molecule uses up its energy by bouncing into other molecules. Oxygen, nitrogen, and more water, if it is in the Earth's atmosphere. Eventually it doesn't have enough energy to stay a gas anymore, and the next time it hits another water molecule, it "sticks". This is what humidity is, liquid water floating around in the air, a few molecules at a time. That's why you get damp when it's humid, the water floating around in the air hits your skin and your sweat and "sticks". It doesn't have the energy it needs to bounce off and float away. On the other hand, if a water molecule were in a vacuum, like out in space, it's likely that it would never hit another molecule of anything. Whatever energy it had, whether it was a solid, liquid, or gas... it would stay that way. On the other hand, a larger object, like a comet, would eventually hit lots of molecules, and give away most of its thermal energy. That's why Haley's Comet is made out of ice. The comet's tail is created by the solar wind when it gets close to the sun, and the ice starts to melt. That's why the tail always points away from the sun.
Once the water vapor starts to lose heat or starts to cool down it turns back into water which is known as condensation.
The process is known as evaporation, where water becomes a vapor and rises into the sky.
stuff and stuff and more stuff
Evaporation is the process of water molecules in liquid water escape into the air as water vapor.
A single water molecule is too small to see. Water vapor is when the molecules begin to condense, several molecules forming together, forming tiny water droplets that are held… aloft by the motion of the air around them.
A water molecule is always a water molecule. Therefore, in every state; solid, liquid, or gas. The molecules still have a central atom of oxygen, with 2 hydrogen atoms attache…d with a single bond and two lone pairs of electrons above the oxygen molecule. Furthermore, the molecular geometry of each water molecule is still the same in every state. the shape is V-shape/bent. Not only are the structures the same, but the density is still the same except when water is a solid form. The solid form of water is commonly known as ice and the density of ice is slightly lower than H20's density of 1. This is why in the arctic icebergs have the ability to float above the surface.
If I'm reading your question correctly the answer is condensation, I believe.
What is the process by which molecules of liquid water escape into the air after becoming water vapor?
This process would be evaporation (notice the "vapor" in evaporation)
