Expansion of water during cooling

The expansion upon freezing is because of the shape of the molecule. the way water molecules tend to link together is actually a very open structure with big holes. That means, theres quite a lot of extra empty space. When water freezes it releases energy because  lots of extra strong bonds can be made.  But it does take up more space.  And so, ice expands when it freezes.
