tabulate the characteristics of the three States of matter rigidity compressibility fluidity filling a gas container shape kinetic energy density
Answers
Answer:
(i) Rigidity : It is the property which helps a substance to retain its shape when force is % applied to it. Solids are rigid while gases, and liquids are not.
(ii) Compressibility: The particles of matter can be compressed or reduced in volume by applying force or pressure. Gases are highly compressible.
(iii) Fluidity : It is the tendency of a substance to flow. Liquids and gases possess fluidity while solids are rigid.
(iv) Filling a gas container: The molecules of a gas move in all directions and due to negligible interparticle force of attraction can fill the container.
(v) Shape: Solids have definite shape whereas liquids take the shape of the container in which they are placed and gases do not have any shape.
(vi) Kinetic energy : It is the energy possessed by the particles due to their motion. The particles of a gas have maximum kinetic energy due to free motion of gas particles in all directions.
Solids have minimum kinetic energy due to least movement of particles.
(vii) Density : Density is the mass of a substance per unit volume. Solids have highest density since their molecules are closely packed.
