The degrees of freedom of a molecule of a triatomic gas are
NTA AbhyasNTA Abhyas 2020
Solution:
As temperature requirement is not given so, the molecule of a triatomic gas has a tendency of rotating about any of three coordinate axes. So, it has $6 \, $ degrees of freedom; $3$ translational and $3$ rotational.
Thus,
( $3$ translational+ $3$ rotational) at room temperature.
