Pinyin/Liquid
< Pinyin
A liquid is a form of matter. It is settled between solid and gas. Liquid has an almost fixed volume, but no set shape.
Every small force makes a liquid change its shape by flowing. Because of that, gravity makes liquids always take the shape of the container. The molecules that make up the liquid can freely move among themselves.
