Chemistry - Thermodynamics - I Question with Solution | TestHub

If all the gas molecules are assumed to be rigid spheres of negligible volume, the only possible molecular motion is translational.

In polyatomic molecules, the motion of each atom is independent to the motion of other atoms of the same molecule and the net motion of the molecule is the resultant of motion of all the constituent atoms.

Kinetic and potential energies are independent modes to describe the energy of a particle.

All polyatomic molecules have two rotational degrees of freedom.
