Give the reason for the existence of the three states of matter.

All matters made up of small particles. The arrangement of particles is different in different Matters. The existence of the three states of matter depends on few factors.

• In the case of solids, the spaces between the particles are minimum. Hence the force of attraction between the particles is maximum. Therefore, the kinetic energy of particles is minimum.

• In case of liquids, the spaces between the particles are more than solid. The force of attraction between the particles is less than solids. Therefore, the kinetic energy of particles is more than solids.

• In the case of gases, the spaces between the particles are maximum. Hence the force of attraction between the particles is more. Therefore, the kinetic energy of particles is maximum.
