S.No Property Solid Liquid Gases
1. Shape They have a definite shape They do not have a definite shape They do not have a definite shape
2. Volume They have a definite volume They do not have a definite volume They do not have a definite volume
3. Density They have high-density Liquids have less density than solids Gases have the least density
4. The kinetic energy of particles Least More than solids Maximum
5. Compressibility Negligible Low High
Rigidity: It is the property of matter to resist the change of its shape.
Compressibility: It is the property of matter in which its volume is decreased by applying force.
Fluidity: Matter can flow.
Filled a gas container: On filling, a gas takes the shape of the container.
