Solution

S.No	Solid state	Liquid state	Gaseous state
1	Definite shape and volume	No definite shape. Liquids attain the shape of the vessel in which they kept.	Gases have neither a definite shape nor a definite volume.
2.	There is little space between the particles of solid.	These particles have a greater space between them.	The space between gas particles is the greatest.
3.	Incompressible	Compressible	Highly compressible
4.	These particles attract each other very strongly	The force of attraction between liquid particles is less than solid particles	The force of attraction is least between gaseous particles.
5.	Rigid	These particles move freely	Gaseous particles are in a continuous, random motion.
