Water, unlike almost all other liquids, actually expands about 9% once its freezing point is reached. This creates an open molecular structure, so it is less dense than when it is liquid.
Water is at it's densest at 4 degrees Celsius.

∙ 13y agoBecause the stuff water is made out of (yeah don't ask...I don't know the names of stuff like that haha) expands when the temperature drops. Since there is more space between them that makes it less dense
Yes - when frozen, water molecules line up rigidly to form crystals, and when the ice melts, the molecules are free to slide around each other. Picture a house of cards as water ice, and then knock it over and that's liquid water.

Does polar water diluted by melting ice become less or less dense?
less denser than
Does Ice floats in water because water molecules in ice are more tightly packed than in liquid water?
Ice floats because it is less dense than water. When water freezes, it creates a crystal lattice that occupies more volume than the water did. Because it is less dense, ice is displaced by water (and floats on top). If enough ice is forced below the surface by its weight, you can have ice on top and ice below (as in an iceberg).
How does the density of water change as a function of temperature?
Water is most dense at +4 deg centigrade. When it freezes it becomes lighter.
What is the chemistry behind ice?
It is still H2O, only the particles are much more dense. I disagree, If ice were LESS dense than water, it wouldn't burst pipes when the water freezes. For those needing further proof, ice floats on water, so it has to be less dense.
Is chalk less dense than salty water?
No, it is more dense. If it were less dense it would float.
When water freezes it expands and becomes more or less dense?
It becomes less dense. Ice will float on water
Experiment for which liquid freezes the fastest?
water because its less dense
Is ice denser than cold water?
no, when water freezes it becomes less dense, that is why ice floats.
Which is denser ice or cold water?
Cold Water. Water expands when it freezes, which makes ice less dense.
How dose freezing cause water to become denser?
When water freezes, its molecules lose energy and get stuck in a lattice structure in which they are farther apart from each other than in their liquid state, thus making ice less dense than water
Does polar water diluted by meltings ice become more or less dense?
less denser than
Where cool dense water sinks does it become more dense?
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
Are most materials more or less dense in their solid state than in liquid?
More dense. As a solid is formed the particles vibrate less and group closer together. One of the only exceptions to this is water. When water freezes and becomes a solid it becomes less dense which is why ice will float in your drink.
Where cool dense water sinks it become more dense?
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
What is the role of hydrogen bonds in ice?
In ice, each molecule of water is hydrogen bonded to four other water molecules, forming a hexagonal crystal lattice. This structure causes the ice to increase in volume and become less dense when it freezes.
What happen as water changes into ice?
In ice, each molecule of water is hydrogen bonded to four other water molecules, forming a hexagonal crystal lattice. This structure causes the ice to increase in volume and become less dense when it freezes.
Is water denser when it's frozen than when liquid?
No. I*f it were, ice would sink in a glass of water. As water freezes, it expands, and becomes less dense.
