Detailed Solution

A triatomic molecule can bodily move along a straight line . Also it can rotate about an axis . For nonlinear triatomic molecule moment of inertia is not zero about any axis and hence rotational kinetic energy is not zero about any axis,If an ideal gas contains a very large number of triatomic nonlinear molecules , the molecules have three translational and three rotational degrees of freedom .
