deltaH= ___?____ kJ/mol
heat capacity of H2O(l) = 75.2 J/mol⋅K = 0.0752 kJ/ mol.K
heat capacity of H2O(s) = 37.7 J/mol⋅K = 0.0377 kJ/ mol K
heat of fusion = -6.02 kJ / mole ( liquid to solid heat releases ) it is at 0oC
at -15 ∘C heat of fusion = -6.02 - (-15 x (0.0752 -0.0377 ))
= -6.02 + 0.5625
= -5.46 kJ
heat of fusion of water at -15∘C = - 5.5 kJ
