Can water preserve itself?

Question

ok. here's the dealio. i was with my friend eating macaroni and i asked "how do they make water" [whoever THEY are...] so my mom was like "its a natural recourse and renews itself." so im like "what if u drink it?" but anyways. lets cut to the chase. if you just let water sit there... will it renew itself? like, become prettier, glowier, clearier or whatever renewing means. :] i know its a pretty stupid question but im randomly curious about it. :]

Answer 1

ummm what? if you leave water sitting it evaporates leaving the minerals behind, once it rains again it rains pure, clean water.

Answer 2

Not that I know of. It'll probably just be the same.

Water has existed for billions of years, we drink the same water the dinosaurs drank.

Cool huh?!

:D

Answer 3

I wouldn't think so.  It would evaporate, but it wouldn't create a fresh cup of water by itself.  When it rains, water flows down a mountain and creates a river, which goes down to the ocean.  The water cycle happens and it repeats.

Answer 4

If you let water just sit there then it stagnates and is nasty.  It will only evaporate if it is warm or hot.  The world gets most of it's drinkable water from lakes and even the ocean.  When it is hot (the ocean normally is) then the water does evaporate in the atmosphere and is carried by rain clouds to wherever and then is dumped (rained down) on that area filling lakes and stuff.  Then the water is sent through our treatment plants and made safe to drink.  Also, when we flush the toilet, that water is sent to treatment plants as well.  I buy spring water though, cause I can't stand the thought of drinking water someone at some time has peed or pooed in.  That is gross.  I don't care how much the city claims to have cleaned it, it will never be clean enough for me.  What were we talking about again...??

Answer 5

If you let water sit... it should evaporate until nothing is left. This might take a few days, depending on the volume, surface area, and temperature of the water. As your mom said, evaporated water is still water, but it's in a gaseous state. Meaning it turns into a gas and floats into the sky and when there's lots of gaseous water, clouds form. Eventually it turns into rain, and you get the water back.

If you're curious how they get large amounts of water that isn't contaminated... usually "they" either find something like a well/spring, which is clean water, and (I assume) boil it to kill germs and run it through a filter, then bottle it. If "they" are taking it from the ocean, in order to get rid of the salt, they evaporate the water in one room, condensate it back into liquid form in another room, and all the salt and other minerals are left behind.
