Answer:
A solid has a definite shape and volume.
Solids in general have higher density.
In solids, intermolecular forces are strong.
Diffusion of a solid into another solid is extremely slow.
Solids have high melting points.
Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. ... It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.
