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