Final answer:
A liquid takes the shape of its container, forms a horizontal surface, and has a fixed volume.
Step-by-step explanation:
A liquid is described by the following properties:
Takes the shape of its container: Unlike solids, liquids do not have a definite shape and will conform to the shape of the container they are placed in.
Forms a horizontal surface: Liquids have a free surface, which is always horizontal when the container is at rest.
Has a fixed volume: Liquids maintain a constant volume, meaning they do not compress or expand significantly under normal conditions.
