Why does water expand when it freezes? Why does liquid water have a density
maximum? Most liquids have a quite simple behavior when they are cooled (at a
The fact that water expands upon freezing causes icebergs to float. The fact that
water reaches a maximum density at about 4°C causes bodies of water to freeze

Jul 6, 2011 ... Why does ice float in the cool summer drink of your choice? And why don't ponds
and lakes freeze from the bottom up, killing all the fish?
Water expands by a factor of 112, or roughly 9 percent, when it freezes. Water,
unlike most other liquids, forms stronger hydrogen bonds as temperatures drop.

Overview. The reason that water expands when freezing is that when it is
near its freezing temp (below 4°C), the hydrogen bonds between water
Dec 6, 2014 ... The molecules of most elements are more compact in their solid form than they
are in their liquid state, but water is different. As you may know, ...
Imagine you are trying to find a place to stand on a crowded dance floor. The
floor is jam .... That's the chemistry reason why water expands when it freezes.
Yes. To prove this to yourself, fill a plastic bottle halfway up with water and freeze
it without the cap on. The put the cap on and let the ice melt. You'll notice that ...
Normally, things expand when heated and contract when cooled. Water is an
exception to this rule. Even though water does expand when heated and contract
