| 3.70 | 179. | A | Stephenson and Malanowski, 1987 | The table in Ref. Kellogg and Cady, 1948 gives the temperatures in °C; however, all of the equations and graphs in the article suggest that the temperature should be in Kelvin. We have assumed that the tabulated temperatures are in Kelvin; the results closely correspond to the entry in Ref. Stephenson and Malanowski, 1987.; AC |
Antoine Equation Parameters
log10(P) = A − (B / (T + C))
P = vapor pressure (atm)
T = temperature (K)
