A gas is a state of matter that takes the shape of its container. Gas particles are free to move around and fill the space available to them, allowing the gas to expand or be compressed to fit the container's shape.
Gas is one of the four fundamental states of matter (with solid, liquid and plasma being the other states). It has the distinction of taking both the shape and the volume of the container that it is in. If you want to include plasma, that too will expand - acting like a gas. So will supercritical fluids which might be considered gases by some definitions, but not by others..
The matter that takes the shape but not the volume of its container is a gas. Gases have particles that are far apart and move freely, allowing them to fill the shape of their container but not have a fixed volume.
Both a gas and a liquid will take the shape of its container.
