Does a Liquid Form an Upper Surface?

A liquid flows and takes the shape of a container, except that it forms a flat or slightly curved upper surface when acted upon by gravity. ... A gas takes both the shape and volume of its container. Figure 1. The three most common states or phases of matter

phases of matter

are solid, liquid, and gas.

Does a liquid have a upper surface?

Gases have no definite shape or volume. Liquids have one free upper surface only.

Do solids conform to the container shape?

A solid has a fixed shape and volume that do not change with the shape of its container. Consider a rock and how its size and shape stay the same, regardless of where you put it. A liquid has a constant volume, but its shape conforms to the shape of its container.
