They are called gases.
Substances that assume the shape of their container but do not have a definite size is water or any liquid substance.

irregular shapes Depending on your reference they may also be fluids if they are not a solid figure.
This describes the physical property of liquids. Liquids take the shape of their container because their molecules are free to move past one another, but they do not have a definite volume like solids do.
