Damn it go read the Law of Conservation.

It depends upon what you mean by "more." If you are talking in terms of density, water is the densest in the liquid form, which is why it is different from most other types of matter, which are generally more dense in the solid form. The reason behind this is due to intermolecular bonding and that each water molecule has the capability of forming 4 hydrogen bonds. Oddly enough though, cold water is more dense then warm water, which actually causes oxygen turnover in bodies of water.

Now, if you talk about "more", in terms of surface area, water expands when it freezes. Therefore, frozen water, or ice, will yield the greatest volume. A simple experiment to prove this is to fill a plastic bottle up with water to the brim. Put the cap on and then put it in the freezer. Overnight, the bottle will expand in girth, possibly even exploding.

you see if water go's below a certain tempreature it will eventually freeze, thereby becoming a solid. there after nno matter how cold you get it will forever remain a solid unless of course HEATED to then again be a solid. however if you heat water, yes it will eventually evaporate into cloud, or whatever and will only be brought back into liquid forms if it COOLS down, this one really baffles me. could you prehaps help!!!

"Water, water everywhere,

And all the boards did shrink;

Water, water everywhere,

Nor any drop to drink."

The thing that is most like "water" is the substance, unsuprisingly called; ...water.

Water comes in three obvious states, depending on it's temperature:

Solid; absolute zero - 0 degrees C = ICE

Liquid; 0 degrees C - 100 degrees C = (there's no special name for this type of water, exepct perhaps, Evian, Volvic etc... so we usually just call it WATER)

Gas; 100 degrees C+ = WATER VAPOUR.

In each state, the substance is still made up from one oxygen atom and two hydrogen atoms. The term 'water' has this specific chemical meaning, which applies whatever the physical state of the substance.

Ice is water

Water vapour is water

Water is water

Anyway, back to the orriginal question;

"is water more water when hot or when cold?"

As stated, water is no more 'truly' water, whether it is ice or vapour.

And it's certainly no MORE, quantitively speaking (although gasses are less dense, and expand, and water molecules, unusually, also have a tendency to cause a net increase in volume when frozen... so I suppose, water is MORE water when it's ice or gas...)

Christians like this handy little 'trinity of water' to describe the three aspects of their God, which is nice. (I do wonder though, if God was a duality before Christ was born?)

But I don't think water becomes any truer water, whether hot or cold.

neither cos when it is solid it is ice and when it is gas it is steam they all have slightly different properties therefore are different things

Water, I think, is more water when cold. That's when you get to enjoy it. It evaporates when hot so cold water is more likely to remain water than hot water. Hot water burns though it has its uses but cold water has this serenity and poise. That's when, I think, it's 'friendly' & we can swim in it & play with it. That is when we enjoy water.

water is water whether its cold or whether its hot in summers as nobody can live without water water is precious whether in mawsynram or in sahara desert its water , paani , h20 or its in any language its water water water

I don't like this question because it challenges me. I'm baffled. Ask a scientist.
