| Mar 14, 2019 at 10:05 | comment | added | Vishal Jain | It is closer to my measured value, its just that 9/7 is closer to the values listed in the tables of my textbook. | |
| Mar 14, 2019 at 9:57 | comment | added | Vishal Jain | @Alchimista If vibrations are not available at low temperatures then that implies a C02 molecule only has 5 degrees of freedom which gives the incorrect value of gamma. Can you please clarify what you mean by "Carbon dioxide sp. heat ratio is accounted for the fact that the vibrations are not available at low temperature." | |
| Mar 14, 2019 at 9:35 | comment | added | Alchimista | Carbon dioxide sp. heat ratio is accounted for the fact that the vibrations are not available at low temperature. It is cross posting through it seems you assert opposite things. In chemistry you said vibrations must be accessible to get 1.3 | |
| Mar 14, 2019 at 8:34 | comment | added | Matteo | I think CO2 can't be considered as an ideal gas, since interaction between molecules is note negligible (as it is in Helium and N2 gases). The interactions modify $U(T)$ and consequently the specific heat ratio $\gamma$. | |
