Question

what do we call the motion of particles in solids​

Answer 1

Answer:

In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... In the solid the particles vibrate in place.

Answer 2

The particles in a solid are tightly packed and locked in place. Although we cannot see it or feel it, the particles are moving = vibrating in place. The particles in a liquid are close together (touching) but they are able to move/slide/flow past each other.
