* Shape: Liquids take the shape of their container. Pour water into a glass, and it becomes the shape of the glass. Pour it into a bowl, and it takes the shape of the bowl.
* Volume: While the shape changes, the volume of the liquid remains constant. A gallon of water is still a gallon of water, no matter what container it's in.
Other states of matter:
* Solids: Solids have a definite shape and volume. A rock will stay the same shape and size unless acted upon by an outside force.
* Gases: Gases have no definite shape or volume. They expand to fill the entire container they are in.
