42.4 ± 1.3 | 279. | Stromsoe E., 1970 | Heat capacity at 279 K was obtained by thermal conductivity [ Halford J.O., 1957]. Vapor heat capacities from calorimetric measurements [ De Vries T., 1941] were converted to the ideal gas heat capacities by corrections for the gas imperfection effects [ Chen S.S., 1977, Chao J., 1986, 2]. Ideal 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 1.17 J/mol*K. The accuracy of the experimental heat capacities [ Stromsoe E., 1970] is estimated as less than 0.3%. Please also see De Vries T., 1941, Weltner W., 1951, Halford J.O., 1957.; GT |
