Question

The degrees of freedom of a molecule of a triatomic gas are

• A. $2$
• B. $4$
• C. $6$
• D. $8$

Answer 1

Answer: (C)

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.
