Equation (2) shows that fusion enthalpy comprises two contributions: one related to the vapor pressure of the component and the other related to the sublimation pressure. Therefore, the limits of the aplicability of the method depend on the limits on these two quantities.
The sublimation pressure is calculated from the IAPWS-08 (IAPWS 2008) sublimation pressure equation [p.sub.sub.sup.08] (T).
The sublimation temperature ([T.sub.sub.sup.08]) is calculated for given pressure p by solving iteratively the sublimation pressure equation (Equation 8) in terms of [T.sub.sub.sup.08] = T.
For temperatures T [less than or equal to] 273.75 K, [p.sub.w,s] = [p.sub.sub.sup.08] (T) is the sublimation pressure from Equation 8 of IAPWS-08 (IAPWS 2008).
Whatever is freeing the dust -- be it mere sublimation of the ice that traps it, electrostatic "levitation," or sudden bursts produced by the exposure of ices whose sublimation pressure is lower than that of water ice -- the expansion of the area covered by dust provides a conspicuous signature.
