Answer» Correct Answer - C Oxygen is a diatomic gas and hence has 5 degree of freedom 3 trenslational and 2 rotational . As the heat is given to oxygen `C_(v)` increases from `(5R)/(2) "to" (7R)/(2)`. Hence , internal energy `(DeltaU=nC_(v)DeltaT)` increases. With the increases in internal energy the atoms within the molecule may also vibrate with respect to each other .In such cases the molecule will have an additional degree of freedom due to vibratinal motion.
