Verified answer
Solid state ;-» Inter particle spaces :- very small, particles are closely packed.
» inter particle forces ;- very strong.
» Nature :- very hard and rigid.
» Compressibility :- Negligible.
» Shape and Volume :- definite shape and Volume.
» Density :- High
» Molecular Motion or kinetic energy :- Low
» Diffusion :- Negligible
-----------------------------------------------------
Liquid state :-
» Inter particle spaces :- comparatively large , particles are loosely packed.
» inter particle forces ;- weak
» Nature :- Fluid.
» Compressibility :- very small
» Shape and Volume :- Indefinite shape but defnite volume.
» Density :- less than the density in solid state.
» Molecular Motion or kinetic energy :- Comparatively High.
» Diffusion :- Slow.
-------------------------------------------------------
Gaseous state :-
» Inter particle spaces :- very large, particles are very loosely packed.
» inter particle forces ;- very weak.
» Nature :- Highly fluid.
» Compressibility :- Highly compressible.
» Shape and Volume :- Indefinite shape as well as volume.
» Density :- very low density.
» Molecular Motion or kinetic energy :- Very high.
» Diffusion :- Very fast.
