answered-by-expert Expert Answer

  Solid    Liquid   Gas
Free Surface Solids have infinite free surface. Liquids have one upper free surface.   Gases do not have any free surface.
Molecular motion Solid particles vibrate only about their mean position.  Liquid particles are free to move around in the liquid only. They can slip and slide over each other.  Gaseous particles move with high speed in all directions and can exert pressure on the walls of the container.
