Question

How do particles tend to move in solids? Please 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.

Answer 1

They vibrate abour fixed points.

Since particles have charges that attract each other it stays intact.

Answer 2

Answer: Option (d) is the correct answer.

Step-by-step 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.
