WebNov 13, 2024 · The 8.314 J/ (mol K) especially links between free energy and temperature, which is why in equations like G = -RTln (K), you use R = 8.314 J/ (mol K). Also the two R values are equivalent as seen by the following: 0.082 L atm/ (mol K) * 101325 Pa/1 atm * 1 m^3/1000 L * 1 J/ (Pa * m^3) = 0.082 * 101.325 J/ (mol K) = 8.31 J / (mol K). WebR = the universal gas constant = 8.314 J/mol K,; T = the absolute temperature; M = the molecular weight of the gas in kg/mol; γ = the adiabatic constant, characteristic of the specific gas; For air, the adiabatic constant γ = 1.4 and the average molecular mass for dry air is 28.95 gm/mol. This leads to

WebJun 13, 2024 · Traditionally, however, this constant is given a different name; it is Boltzmann’s constant, usually given the symbol k. (2.7.1) k = R / N ¯ = 1.381 × 10 − 23 J K − 1 m o l e c u l e − 1. This means that we can also write the ideal gas equation as P V = n R T = n N ¯ k T.

WebHeat 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 ].
