What happens to molecules in a liquid when it becomes a solid?

Since the liquid becomes a solid all the molecules will then begin to stick together and wont move out of its place.

Liquid molecules generally have spaces in between them. Molecules in liquids move freely compared to solid molecules. When a liquid turns into a solid its molecules organize in a specific arrangement that take up more space. This freezing process makes molecules act closer together forming a compact solid structure. It is important to note that the number of molecules in solid water is still the same; the order in which they are arranged only differs. Due to this solid water becomes less dense than liquid water.
