18.44 (a) Calculate the specific heat at constant volume of water vapor, assuming the nonlinear triatomic molecule has three transla- tional and three rotational degrees of freedom and that vibrational motion does not contribute. The molar mass of water is 18.0 g/mol. (b) The actual specific heat of water vapor at low pres- sures is about 2000 J/kg K. Compare this with your calculation and comment on the actual role of vibrational motion.
