Study Cards on molecules, density, regular

What happens to the molecules if you cool down a liquid?
If you allow the molecules time to settle, they can order in very regular arrangements, called a crystal.
The density of a crystal is generally higher (by about 20%) than that of the corresponding liquid, except for?
Ice has a lower density than water.
Why can water crystallize quickly?
Because the small water molecules can quickly reorient themselves to fit in the lattice. For larger molecules this takes longer.
Which molecules often crystallise only partly and how is that called?
Biopolymers that behave like a random chain (no particular shape of the overall molecule). This is called semi-crystalline.
