WebNov 21, 2015 · Looking on the NIST fluid properties database I see that the specific heat capacity (i.e. the heat capacity per unit mass) of D2O is just 1.5% higher than the specific heat capacity of H2O. So at 298 K this makes the molar heat capacity of D2O (84.963 J/K/mol) an astonishing 12.7% higher than H2O (75.38 J/K/mol). WebAbstract. THE marked differences between the physical properties of H 2 O and D 2 O (and of all polar compounds of H and D) cannot be due to intramolecular differences, which are far too small ...
