👉 Matter and fluid are distinct states of matter, each with unique properties. Matter, encompassing solids, liquids, and gases, is composed of atoms or molecules and exhibits characteristics like mass, volume, and chemical composition. Solids maintain a fixed shape and volume, liquids have a definite volume but take the shape of their container, and gases expand to fill any container. Fluids, a subset of matter, flow and take the shape of their container without maintaining a fixed volume. Liquids are incompressible, while gases are highly compressible. Both matter and fluids interact with forces such as gravity and surface tension, but their fundamental differences lie in their structural organization and response to external conditions.
