Molecules are composed of particles. A solid is composed of molecules. I recommend you search the definition of a molecule so you can better understand.
they separate into either molecules or ions.
Movement of particles
Molecules of a substance are in constant motion. Whether you have a solid, liquid, or gas, the particles are moving (but the speed and amount they move differs). Particles of a solid move the least (they basically vibrate), particles of a liquid can flow around one another, and particles of a gas have a lot of space between them because they move in random, constant motions.
A solid has definite shape because when particles in any element are cooled down to it's freezing point (becoming a solid), the particles begin to pack together in a particular pattern resulting in the solid's distinct shape.
When heating a solid to its melting point, the molecules in the solid began to move and slide past one another becoming a liquid.
In any solid the particles have bonds holding the atoms together into molecules, and bonds (or forces) holding the molecules together to form the solid.

Movement of particles
There are strong forces of attraction between particles in a solid.
The molecules in the individual solid particles break free of their regular rigid framework by vibrating more energetically. Eventually the particles of the solid lose their shape and fuse together as a pool of liquid.
Solid
the reason is because the molecules casing the pressure inhibit the molecules of the material.
The components of the solid material (atoms or molecules) are ordered in a a crystal lattice.
In SOLIDS, molecules are most tightly bonded together.
It depends which state of matter you are referring to -- solid, liquid or gas. Solid: molecules vibrate in place Liquid: molecules are moving faster than a solid but slower than a gas. gas: molecules are moving at a high speed hope this helps :)

Solid have definite shape because the particles of solid are closely packed together and they cannot move freely. Therefore the force of attraction of particles in solid is more.
