With regard to th A. Complete order of molecules

B. Complete disorder of molecules

C. Random motion of molecules

D. Fixed position of molecules

Answer :

As compared to the solid state as well as the liquid state, we find that in the gaseous state, the molecules have very high randomness in their motion, that is they do not follow any particular direction and similarly there is a disorder-ness in their motion.

This is due to the high entropy which the molecules present in the gaseous state possess. This entropy is the degree of randomness of the motion of the molecules. So more the entropy, more would be its disorder-ness or the randomness of the motion of the molecules.

From the diagram, we can see how there is disorder-ness or randomness in the motion of the gaseous molecules which is lesser for liquid and least or absent in solids.
