Which statements describe the arrangement of particles in solids?

• particles are moving in all directions

• Particles are arranged in an orderly manner

• particles can slide over one another.

• particles vibrate about their positions

Arrange the strength of the forces of attraction between the particles of solids, liquids and gases from the strongest to weakest

• (strongest) gases > liquids > solids (weakest)

• (strongest) solids > liquids > gases (weakest)

• (strongest) gases > solids > liquids (weakest)

• (strongest) solids > gases > liquids (weakest)
