Comparable characteristics of three states of matter part-2

Table comparison of the characteristics of three states of matter- 
s.no 
characteristics 
Solid  
liquid 
gas 
1 
nature 
Very hard and rigid due closely packed particles 
Fluid 
-Substance which flows 
Highly fluid 
2 
shape 
fixed 
Not fixed 
Not fixed 
3 
Volume-space occupied by matter 
definite 
definite   
indefinite 
4 
Density-the ratio of mass and volume =M/V = Kg/dm-3 
high  
Less than the density in solid state 
Very low density 
5 
Interparticle spaces-the space or gap present mong the particles in matter  
Very small, particles are closely packed 
Comparatively large , not so closely packed particles 
Very large 
6 
Compressibility-particles compressed on applying pressure 
Hardly compressible
 due to very small spaces among the particles
Compressible than solid having larger interparticle distances compare to solid 
Highly compressible due to large interparticle distances in gaseous state 
6 
Inter particle force or inter-molecular force- the force experienced by particle in matter 
Very strong  
Weak  
Very weak 
7 
Molecular /particle motion 
Low due to stronger attractive forces exerted in particles 
Comparable high 
Very high 
8 
Kinetic energy –energy required to keep the motion of objects. It increases with increase the temperature. 
Low or negligible 
high 
Very high due to very weak inter particle forces 
9 
Diffusion –intermixing of particles or when particles of one substance occupy the vacant spaces present in the particles of the other substance  is  called diffusion 
Negligible due to closely packed particles having not so spaces among them   
slow 
Very fast due to very large space and very weak forces
