How to explain the molecular attraction is higher and faster in particular object

Answer 1

Intermolecular forces (IMF) are the forces which mediate interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighboring particles, e.g., atoms or ions.

The particles (atoms or molecules) are attracted to each other. The particles (atoms or molecules) vibrate but do not move past one another. The solid retains its shape.

The kinetic theory of matter helps explain the different states of matter—solid, liquid, and gas. The particles in a solid, such as concrete, are not free to move around very much. ... Particles do not always move at the same speed. Within any group of particles, some are moving faster than others.
