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 ]. 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. Because the number of molecules in the sample, N, is N = n N ...
