State of a substance is basically a function of interparticle forces.
eg H2O exist as liquid at room temperature while H2S is a gas. This is because intermolecular forces in water are stronger than in H2S .
So is the case of most of ionic compounds as ionic inieraction between oppositely charged ions is strong enough to make them a solid at room temp.
On the basis of interparticle forces only interparticle space is defined.
Energy of particles is a function of temperature. As water also exists as steam when temp. is raised because molecules gain energy to overcome intermolecular forces.
