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 state of matter that changes shape when placed in a different container is water
The state of matter that keeps the same volume but changes shape when it changes container is a liquid. Liquids do not have a fixed shape but take the shape of their container due to their ability to flow and fill the container.
The matter state with a definite volume but an indefinite shape is a liquid. Liquids take the shape of their container but maintain a constant volume.
The state of matter that keeps its shape and volume in a container is a solid. Solids have a definite shape and volume because their particles are tightly packed and have little room to move around.
A liquid is a state of matter that has a definite volume but no definite shape. Liquids take the shape of their container but maintain a constant volume.
Liquid. You can measure the exact volume of a liquid but you can put it into containers that changes the shape of the liquid.

The state of matter that maintains both shape and volume when placed in a different container is a solid. Solids have particles that are tightly packed together, giving them a fixed shape and volume.
