Constant pressure heat capacity of gas

Cp,gas (J/mol*K) Temperature (K) Reference Comment
133.4 ± 1.1360.55Stromsoe E., 1970Ideal gas heat capacities are given by [ Stromsoe E., 1970] as a linear function Cp=f1*(a+bT). This expression approximates the experimental values with the average deviation of 1.13 J/mol*K. The accuracy of the experimental heat capacities [ Stromsoe E., 1970] is estimated as less than 0.3%.
