Internal energy is the energy associated with the random, disordered motion of molecules. Internal energy is the sum of the kinetic and potential energies of the molecules.

The various energies which contribute toward the internal energy are:

  1. Translational energy of the molecule
  2. Rotational energy of molecules
  3. Vibrational energy of molecules
  4. Intermolecular energy
  5. Energy associated with bonds within the nulceus
  6. Potential energy of molecules

It is not possible to determine the absolute values of the above energies since all these are microscopic energies of the molecules. Thus the absolute value of the total internal energy of the system cannot be determined.
