Answer» (a) All the molecules of a substance are identical. (b) The inter-molecular spacing is least in solids more in liquids and still more in gases. (c) The molecular motion in liquid and gas is in zig-zag path. (d) In a solid, the molecules vibrate to and fro but they remain at their fixed positions. (e) The inter-molecular forces are the weakest in gases. (f) A solid exerts pressure downwards on its base. (g) The gases are least dense. (h) A solid is most rigid.
