Answer 2

Answer:

(i) it is called the intermolecular space between the molecules.

(ii) Molecules of a gas has maximumintermolecular spaces. 

(iii) When a solid absorbs heat the energy is stored in form of vibrational energy of the atoms or molecules, its a form of kinetic energy. In case of liquids and gases one can observe the actual motion of atoms/molecules. All these observations are found at the atomic level.
