(N/A) The state of matter in which layers of particles can slip and slide over one another easily is the liquid state. In liquids,the intermolecular forces are weaker than in solids,allowing particles to flow.
$(b)$ The state of matter in which particles move around randomly due to very weak forces of attraction is the gaseous state. In gases,the intermolecular forces are negligible,allowing particles to move freely and randomly in all directions.
