a) How many rotational degrees of freedom are there in a CO2 molecule and in a H2O molecule? b) If the temperature of a low-pressure CO2 gas is raised high enough to completely excite its rotational and vibrational modes, what will be its specific heats cv and cp? Express answers in both kJ/kg K and kJ/kmol·K.
