Answers
Answer : 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.
Shape: Having definite boundaries.
Kinetic energy: It is the energy possessed by the particles of matter due to its motion.
Density: It is the ratio of mass with per unit volume
