A) SOLID STATE - 1) Definite shape and volume 
                         2) Incompressible 
                         3) There is little space between the particles of a solid 
                         4) These particles attract each other very strongly .
                         5) Particles of solid cannot move freely 
LIQUID STATE -1) No definite shape liquid contain the shape of the vessel                                       in which it is kept .
                         2) compressible to small extent .
                         3) These particles have greater space between them .
                         4) The force of attraction between liquid particles is less than . 
                              solid particles .
                        5) these particles move freely 
GAS  STATE  - 1) Gas have neither a definite shape nor definite volume . 
                        2) highly compressible 
                        3) the space between gas particles is the greatest .
                        4) the force of attraction is least between gaseous particles 
                        5) gaseous particles are in a continuous randam motion.
b) rigidity can be expressed as the tendency of matter to resist a change in shape . compressibility  is the ablity to be reduced to a lower volume when force is applied . fluidity is the ablity to flow.by filling a gas container we mean the attainment of shape of the container by gas.                                               
shape defines a definite boundary.                                                                   kinetic energy is the energy possessed by a particle due to its motion.              density is mass per unit volume.
