How do particles in a solid differ from particles in a liquid?

The particles in a solid are tightly packed and locked in place, The particles in a liquid are close together (touching) but they are able to move/slide/flow past each other. The particles in a gas are fast moving and are able to spread apart from each other.

particles in a solid are closely packed together and vibrate, rather than move freely, whereas in a liquid particles are further spread apart and move around

Explanation:

particles are always moving, but in the three different phases (solid, liquid and gas) they move at different speeds. in a gas they vibrate, in a liquid they begin to move more openly and freely because the particles are more spread out and then in a gas the particles are racing around because the particles are even further spread apart
