Dumb question!

[Marko pro]

So water is in liquid state, ice is in solid/strongly state, aerated water is gas then what's the snow? Snow has some connection with water, don't it?

I confused there, has some1 meaningful response?

maybe ice is crystal and snow is solid? o.O

[NinjaExplosive]

snow is pretty much just ice crystals forming around tiny specs, so it's solid..I think :P

[MnM]

Correct me if i am wrong, aerated water is more like a colloidal solution of gas in liquid :o . I have never seen snow. I think its a solid though.

as Ninja said above, snow is ice crystals formed together. When they fall depending upon temperature in the air snow will remain solid or would have melted.
But once solidified it is called hail, and if melted it is rain.. Together it is sleet.
So snow as we know it, then will be a semi-solid.
As the the wet solid melts when it touches a hot body
Hence it is safe to assume snow is a semi-solid

[Gespenst]

Snow is solid form of water that crystalizes in atmosphere.

Maybe you should google for better answer.

To fully understand the difference between a liquid and a solid, you'll have to look at it at the atomic level. To make it all nice and smooth, we look at the water-molecule H₂O (and not some weird tap water which has minerals and stuff dissolved in it):


The fat sphere is the oxygen, the smaller ones are hydrogen. Now, what does this tell us about its state? Nothing

It is about the connection between the individual molecules that defines the form. If you have single H₂O-molecules floating freely around, with practically no interaction between each other, you have a gas (aka. water vapor).

Push these things a little closer together so that weak bonds can form. You'll get a terrible mess of molecules that are oriented in any way. They somehow stick together but not really strongly. That's liquid water.

The temperature is directly linked to the speed these molecules move along. The lower it is, the slower the molecules. In gas-phase, they are so fast that no bound can form but the colder it gets, the more bonds are there that are not broken up again.

At cool temperatures, most stuff crystallizes into some sort of regular shape¹⁾. For water/ice, it kind of looks like this:



You basically get some symmetry into the water. According to thermodynamics, things want to end up as chaotic as possible, so this ordered structure is actually kind of against it (but it has the best energetic conditions of the individual molecules, so there is some kind of equilibrium). Long story short, the ordered condition can be seen somewhere else, too:



Looks pretty ordered, too. In fact, snow flakes are little water-crystals. Therefore, they're solid.

Aerated water, on the other hand, is just liquid water where you slap some bubbles into. You wouldn't want to call that "gas", would you?

¹⁾ Quantum Mechanics disallows a state of complete rest. This means, stuff has a zero-point-energy which prevents Helium from crystallizing, unless you force it into some really awkward conditions.


And yay, Blue Phoenix's longposts strike once again!

So water is in liquid state, ice is in solid/strongly state, aerated water is gas then what's the snow?

First of all, all of this is water - no exceptions.
Second, there are exactly 4 different kind of phases for water:
solid,
liquid,
gaseous
and super critical (nothing you will ever encounter for water I hope)
wikimedia.org//Water_phase_diagram.svg (For a better understanding of this diagram: imagine a horizontal line (our atmospheric pressure) just above the TP point. You have 0 °C where it crosses the left red line and 100 °C crossing the right red line, in between = liquid water.)

The first three are your common ones and pretty self explanatory.
Snow is of course the solid phase, except not your usual huge chunk covering a lake or swimming in your drink.
It's just a lot of small pieces, like sand. Go and put a snow flake under a microscope yourself (do it outside/cool it down so it doesn't melt instantly). They can have a lot of cool shapes like the one BP posted.

The tricky thing that probably confuses you is that snow (or ice) if put under pressure becomes liquid, without actually heating it.
(You can also see that inside the phase diagram I posted: If you start anywhere inside the solid area and increase the pressure (going up) you will cross the red line into the liquid area)
This is because water has its highest density at 4 °C, in its liquid phase. This may be abnormal as most other substances are more dense as a solid, but it's one of the many exceptions that make life possible the way we know it.

Here are some cool things you can explain with it:

If you fill a bottle with water, close it, and put it in the freezer ... the water will freeze to ice, thus expand, and break the bottle.
If you walk over ice the weight of your body (pressure) will melt the top layer of it, forming a small liquid film that will make you slide (otherwise you would be able to walk on ice as if it were concrete).
Lakes always freeze from top to bottom because the liquid has more density and ice cubes will always float in water because of their lower density.

They somehow stick together but not really strongly. That's liquid water.

No.
Water sticks together very strongly, which is the reason why it has such a high density as a liquid and also the reason why it does not mix with oil.
This is also the reason why it forms droplets on a surface and why you can fill a glass of water a little above the rim without spilling.
If you want to fix yourself there BP why not tell us a little more about those funny spheres you posted?

The fat sphere is the oxygen, the smaller ones are hydrogen. Now, what does this tell us about its state? Nothing

Because if you know their characteristics this tells us a lot about its state. However totally not required to answer the question.

Correct me if i am wrong, aerated water is more like a colloidal solution of gas in liquid :o .

Whenever you are not able to distinguish the liquid parts from the gaseous ones you are right (per definition for colloidal solutions = homogeneous).
However as soon as you can see liquid droplets flying around, which is usually the case, you are not. Because of the strong bonds between water molecules in a liquid state it condenses really fast, even within the air without a surface. Thus you can see liquid water flying around:

Thanks for the lesson, administrator blau Phönix!
Even if one doesn't go to school, it's impossible to escape learning :P

Aerated water, on the other hand, is just liquid water where you slap some bubbles into. You wouldn't want to call that "gas", would you? :P

"Aerated" sounds as though somebody tried to rate the air
Water vapour would be a gas, right?

At least it's not 7293 words :P

You wrote much more than i expected and i needed cuz i already knew almost all this stuff (i am going in chemistry school for chemical technician) This are basic of basic for me :P

but thank you all especially YinYin and BP.

I realized what snow is
also if i can add smthg..

Snow is created in the clouds with long and slow process of sublimation
EDIT response: yes indeedˇˇ

[qwertz143]

Snow is created in the clouds with long and slow process of sublimation

yupp, but how you ask, water particles, through evaporation of seas and oceans attach themselves to hydroscopic nucleii or simply dust particles, which build together and form clouds and in cold countries due to sublimation, that is conversion from gas to liquid in this case, snow is given out
