Why does frozen water take on the pattern it does (hint: it has to do with water’s polarity)?
damaskus [11]

When ice forms, one water molecule's hydrogen atoms form weak hydrogen bonds with the tops of the oxygen atoms of two other water molecules. Lining up the water molecules in this pattern takes up more space than randomly arranging them.

<h3>What is polarity?</h3>

A physical property of compounds that connects other physical properties like melting and boiling points, solubility, and intermolecular interactions between molecules is referred to as polarity.

When ice forms, one water molecule's hydrogen atoms form weak hydrogen bonds with the tops of the oxygen atoms of two other water molecules.

Lining up the water molecules in this pattern takes up more space than randomly arranging them.

When water freezes, the water molecules slow down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern, with molecules further apart than when the water was liquid.

Thus, because of this frozen water take on the pattern it does.

If you wanted a horse to foal in January when would you breed
Nana76 [90]
Since all thoroughbreds have the same birthday — January 1 — the best bet for a racing horse is to raise so that the foal drops right after that date. This means the yearling at his first birthday is a five-year-old and from then on he is ahead of the game with a five year of maturation before each.
