In solids- (i) Particles are closely packed.
(ii) Density is high
(iii) Non compressible
(iv) Particles have low kinetic energy
(v) Infinite no. of surfaces are possible
In liquids-(i)Particles are loosely packed than solid particles.
(ii)Interparticle force of attraction is less than solid
(iii)They have definate mass, volume but indefinate shape
(iv)Kinetic energy of particles is higher than solid
(v)Liquids have only 1 surface area
In gases-(i)Particles are very loosely packed
(ii)Interparticle force of attraction is negligible
(iii)Density is very low
(iv)Gases have no surface area
(v)Interparticle spaces are much than liquids & solids
