Thermal energy is the energy that is associated with the random motion of atoms and molecules in a sample of air. The correct option among all the options that are given in the question is option "4".In
reality it is the Kinetic energy that is making the atoms are moved by the
kinetic or thermal energy. The kinetic energy generated by the individual atoms
within the air is moving in their equilibrium position and it can also be
considered as a great example of disordered energy.
