On the basis of intermolecular forces and thermal energy, explain why substances exist in three different states.

On the basis of intermolcular forces and thermal energy ,explain why (i) a solid has rigidity but liquids do not have rigidity? (ii) gases have high compressibility but liquids and solids have poor compressibility ?

In terms of intermolecular forces, explain why do some substances exist as solids ?

On the basis of intermolecular energy and thermal energy explain why? (i) a solid has rigidity but a liquid does not have rigidty. (ii) gases have high compressibility but solids and liquids have poor compressibility.

Maximum intermolecular forces of attraction exists in

The intermolecular forces in the liquid state of a substance are stronger than those in its solid state.

Assertion (A) Three states of matter are the result of balance between intermolecular forces and thermal energy of the molecules. Reason (R) Intermolecular forces tend to keep the molecules together but thermal energy of molecules tends to keep tham apart.
