Only gases show random motion of particles,

Answer: All states of matter show random motion of particles. ding to the kinetic theory.

Kinetic theory of matter says that all inter particles of a matter in constant rapid motion.

Option: D

Explanation:

Considering this theory, 'all states of matter show random motion of particles' is the correct statement. It is obvious that the particles of gases show more motion as compared to that of liquids whereas the particles of liquids show more motion as compared to solids. As solids are rigid substances, the moment of particles in solids is less.
