If u put a 1L water bottle in the freezer, why his volume expands when it comes solid?

Question

Please explain scientificly

Answer 1

Water molecules are V shaped with the Oxygen molecule at the pointy end, and the two Hydrogen molecules sticking off like the legs. When water is a liquid the molecules can move around and get close to each other, but as the water freezes the molecules get stuck at funny angles to each other.
Think of it like putting silverware away. If you take all the forks and spoons and carefully lay them one on top of another you can fit all of them in a little space, but if you just toss them in the drawer they make a big messy pile.
It's important to remember that the amount of water doesn't change when it becomes ice, it just takes up more space.

Answer 2

Its very simple. When water freezes the molecules enter a crystalline state of alignment. Usually in a flat hexagonal shape. These tiny structures do not fit together as tightly as the individual molecules alone thus taking up more space. This is similar to the difference of sand and rocks in a jar. Each weigh the same, have similar mass but occupy different volumes.The ice formed does not rise to the surface because of air trapped within it (how would you suppose the air got in there?)but more due to the reduction in density created by the expanding water/ice. (The weight of the surrounding water is what makes the ice float.)

Answer 3

Sorry for my english, to begin with.

It's a wonder of nature. Actually, almost every known substance shows the opposite behaviour: their volume decreases when turned from liquid to solid. This special ability water has prevents the whole sea from freezing. As we know from out friend Arquímedes, substances put into a fluid experiment a force upwards equal to the weight of the volume of fluid they move away. This implies substances with a low density float over fluids of higher density. As density is defined as M / V, with M being Mass and V being Volume, the density of water decreases when it becames solid, as Mass remains the same but Volume increases. That implies ice floats over water, thus creating a "barrier" to cold, which prevents the water under the ice to freeze. If water were like any other substance, ice would go down, thus allowing superficial water to freeze, and this ice would go down again... Resulting in the complete freezing of seas at high latitudes.

Now why does water show this strange behaviour? To be honest with you, I don't know for sure, but I presume it's related to the unions amognst their molecules. They are Hidrogen bridges, which have special properties. But again, I'm not sure about this point.

Answer 4

The expansion upon freezing is due to the fact that water crystallizes into an open hexagonal lattice that contains more space than the liquid state. This is a consequence of hydrogen bonding and the polar nature of the water molecules.

Answer 5

because its really a crystaline structure as ice, and it has to do with the density of the actual state of matter. Also, it will expand or contract as a solid depending on the temperature as well. you may be interested in looking at the triple point temp of water....kinda nifty.

Answer 6

because when it freezes, water expands--the structure of ice makes it so the liquid molecules come together in hexagonal shape--network of molecules joining together, allows for an expansion of the water..that is why you are not supposed to fill it all the way to the top before you put it in the freezer!

Answer 7

The water does not "expand".
As the water freezes it traps air which makes up tiny bubbles inside of the ice.
This takes up more room as the water is displaced by the air.
Therefore the freezing water increases area, not size, as it freezes around the air and moves outward to compensate.

Answer 8

Water expands when it freezes, thats just one of the facts of life.

Answer 9

how do you know its a he?
