Table 3.

Comparison of sublimation enthalpies (ΔH_s) and the corresponding temperatures (T) from current study with the literature, theoretical, and original/adjusted ( $\mathrm{\Delta }{H}_s^{\mathit{\text{adj}}}$) NIST WTT (Web Thermo Tables) values. DPO stands for double paddle oscillator, QCM represents quartz crystal microbalance, G⁰ is bulk shear modulus and ρ⁰ is bulk density. All uncertainties listed in the table are standard uncertainties u (0.68 confidence interval). Enthalpy of sublimation for water was calculated by summing the enthalpies of vaporization at 273.16 K (45.1 ± 1.4) kJ · mol⁻¹) and fusion ((6.014 ± 0.07) kJ · mol⁻¹)) listed in the NIST WTT [1].
