In a flexible balloon, 2 moles of $S O_{2}$ having an initial volume of $1 k L$ at a temperature of $27^{o} C$ is filled. ( $S O_{2}$ is a linear triatomic gas). The gas is first expanded to thrice its initial volume isobarically and then expanded adiabatically so as to attain its initial temperature. Assuming gas is ideal and $R = \frac{25}{3} J m o l^{- 1} K^{- 1}$ change in internal energy of the gas in the isobaric process is:
