Properties of Solids:
- In solids, particles are tightly or closely packed.
- Solids are incompressible, meaning the constituent particle is arranged close to each other and because of that, there is negligible space between the constituent particle.
- Solids are rigid, due to lack of space between the constituent particles which make it rigid or fixed.
- Solids have definite mass, volume and shape due to which it has a compact arrangement of constituent particles.
- The intermolecular distance between molecules is short.
- The rate of diffusion in solids is very low.
