Degrees of freedom for a diatomic gas
WebLinear triatomic molecule has three translational degrees of freedom. It has two rotational degrees of freedom because it is similar to diatomic molecule except there is an additional atom at the center. At normal … Web• The potential energy of the “spring” in this vibration gives another degree of freedom. Since it has three degrees of freedom, a monatomic gas molecule should, if equipartition of energy holds true, have average energy 2 3kT, while a diatomic molecule which has seven degrees of freedom should have average energy 2 7kT. We will see later ...
