Quizplus · Accepted Answer

When water becomes ice, the water molecules are arranged in a rigid crystalline structure, which causes them to pack less densely than they do in liquid form. This is why ice is less dense than water and floats on its surface. None of the other choices accurately describe the behavior of water molecules when water becomes ice.
