Solid state materials are most commonly found in our surroundings. The solid state particles are rigid and do not possess fluidity. The particles of solids are bonded together by strong intermolecular forces of attraction due to which the particles do not move to and fro from their mean positions. Solids possess definite shape and definite volume.
