Question

How do molecules move in a solid ?

Answer 1

It depends on the type of solid. All molecules in solid form have what is called vibration movement, meaning the move in fixed positions. In some solids the forces of attraction between the molecules are strong enough to keep the molecules in a relatively fixed position but allow some moment of molecules past one another. but they also move to where you cant feel them.

hope this helped :)

Answer 2

gas vibrate and move freely at high speeds. liquid vibrate, move about, and slide past each other. solid vibrate (jiggle) but generally do not move from place to place.
