Which state of matter has a definite shape and a definite volume?
Solids are characterized by having a definite shape and a definite volume. The particles in a solid are closely packed and have strong intermolecular forces, which give them a fixed shape and volume. Liquids have a definite volume but not a fixed shape, while gases have neither a fixed shape nor a fixed volume. Plasma is another state of matter, but it does not have a definite shape or volume like solids.
