Standard Water Melting and Boiling Temperatures and Enthalpies of the Transitions
Table E5
Water Cryoscopic (Freezing Point Depression) and Ebullioscopic (Boiling Point Elevation) Constants
Kf = 1.86°C·kg·mol−1 (cryoscopic constant) Kb = 0.51°C·kg·mol−1 (ebullioscopic constant)
C°(H2O(l)) = 4184 J·K−1·kg−1 = 4.184 J·g-1·°C-1
C°(H2O(s)) = 1864 J·K−1·kg−1
C°(H2O(g)) = 2093 J·K−1·kg−1
