Intermolecular forces vs Thermal Energy

 

Thermal energy

·      It is the energy of a body arising by motion of its particles/atoms/molecules

·       Is proportional to the temperature of substance.

·      It is the measure of average kinetic energy of molecules of matter

·      Is responsible for movement of particles

·      This movement of particle is called thermal motion

Intermolecular forces vs Thermal Energy

    ·      Intermolecular forces tend to keep the molecules together but thermal energy of molecules tends to keep them apart.

     ·      Three states of matter are the result of the balance between intermolecular forces and the thermal energy of the molecules.

 

·      Gas ----------> Liquid ----------->Solid

Predominance of intermolecular interactions

·      Gas <--------- Liquid <----------Solid

Predominance of thermal energy
