Check the original paper for verification. Next edit →
Line 77: ===Heat Capacity (Ideal Gas)=== <math>C_P[J/(mol.K)] \, = \, \sum a_i - 3237.93 + \left[ \sum b_i + 0.210 \right] T + \left[ \sum c_i - 3.91 \cdot 10^{-4} \right] T^2 + \left[\sum d_i + 2.06 \cdot 10^{-7}\right] T^3</math> The Joback method uses a four parameter polynomial to describe the temperature dependency of the ideal gas heat capacity. These parameters are valid from 273 K to approx. 1000 K.
