* Liquids: Liquids have a definite volume but take the shape of their container. They are characterized by their ability to flow and resist compression.
* Gases: Gases have neither a definite volume nor a definite shape. They expand to fill their container and are highly compressible.
While solids do not fit the definition of fluids, it is important to note that some materials can exhibit fluid-like behavior under certain conditions, like under high pressure or when behaving as a viscous fluid.
