On what factors does the stability of the state of matter depend?

(N/A) The stability of the state of matter depends on two opposing factors:
$(i)$ Intermolecular forces
$(ii)$ Thermal energy
Intermolecular forces tend to keep the molecules,atoms,or ions closer,while thermal energy tends to keep them apart by making them move faster.
At a sufficiently low temperature,the thermal energy is low,and intermolecular forces bring the particles so close that they cling to one another and occupy fixed positions. These particles can still oscillate about their mean positions,and the substance exists in the solid state.
