It expands, which reduces its density.
when water freezes, it expands. Most elements contract when frozen.
When water freezes, its molecules arrange themselves into a crystalline structure which spaces them out more than when they were in the liquid state. This increased spacing causes the volume of ice to be slightly larger than the volume of the same amount of water.
Its very unusual for a substance to expand when it freezes, water is just odd that way. Its just a property of water, its moleucles expand in the area they take up and take up more space.
It actually expands, instead of contracts, for a few degrees below the freezing point.
Water is an unusual liquid in that it expands as it freezes. This can cause it to break a glass container as the water content freezes.
When it freezes.
Water is unusual because it expands as it freezes and ice is less dense then water. This allows ice to float on water. This makes life on this planet possible because water freezes from the top of a lake down and not the other way around. This means that water life can survive in the winter. Also, because ice floats and doesn't sink, the land isn't flooded by the displaced water.
It floats when it freezes.
Cold water freezes faster then warm water.
water freezes at 0 degrees Celsius.
the reason salt water freezes is because of the amount of salt in the water
Because when the water freezes it expands.
