1. 1) A solid has a definite shape and volume. 2) Solids in general have higher density. 3) In solids, intermolecular forces are strong. 4) Diffusion of a solid into another solid is extremely slow
3.Solid is one of the fundamental states of matter which has fixed shape and volume. Upon the application of external force, solids do not undergo deformation and are incompressible.
Examples: diamond, wood, stone, and metals
