How do particles tend to move in solids? explain your answer

they move randomly through the solid and separately from other particles.

they move in orbits around a center.
particles.
they move randomly through the solid while remaining in close contact with other

they vibrate about fixed points.

Option (d) is the correct answer.

Explanation:

Since, it is known that in solids strong intermolecular forces of attraction exists because of which particles are much closer to each other. Hence, they have definite shape and volume.

Particles of a solid are unable to move from their initial position unless an external force is applied to them. So, when no external force is applied then particles of a solid tend to vibrate at their fixed points.

Hence, we can conclude that particles tend to move in solids as they vibrate about fixed points.
