How does the movement of water molecules change when water goes from ice to liquid?

Description : How does the movement of water molecules change when water goes from ice to liquid?

Last Answer : When water goes solid (freezes), the molecules get "locked"together to form the solid phase. These molecules can't move aroundlike they can in liquid water because they are interconnected andimmobile within ... , though is it is possible for somematerials to diffuse into or out of a solid structure.
