In a throttling process, the pressure of an ideal gas reduce by 50%. If C${_p}$ and C${_v}$ are the heat capacities at constant pressure and constant volume, respectively ($\gamma = C{_p}/C{_v}$), the specific volume will change by a factor of
2. 2$^{1/\tiny\gamma}$
3. 2$^{({\tiny\gamma – 1})/\tiny\gamma}$
