Correlation for the Vapor Pressure of Heavy Water From the Triple Point to the Critical Point
A new formulation has been developed to represent the vapor pressure of heavy water (D2O) from its triple point to its critical point. This work takes advantage of several developments since the publication of the best previous formulation: the availability of some new data in the lower part of the temperature range, the adoption of the ITS-90 temperature scale, and the adoption of recommended ...
متن کامل3He Vapor Pressure near Its Critical Point
Between 0.65 K and 3.2 K, the temperature dependence of the vapor pressure P of 3He is defined by the International Temperature Scale of 1990 (ITS-90). However, the ITS-90 vapor pressure equation was not designed to be consistent with the scaling law required for the second temperature derivative of the vapor pressure in the vicinity of the liquid-vapor critical point. In this paper, two scalin...
متن کاملTwo-step vapor-crystal nucleation close below triple point.
We present the results of Monte Carlo simulations of crystal nucleation from the vapor phase. We studied the Lennard-Jones system at conditions close to, but below, the triple point. This system is expected to show surface melting. The nucleation pathway that we observe consists of two distinct steps. In the first step, a liquid droplet nucleates from the vapor. Its nucleation rate depends stro...
متن کاملNucleation and droplet growth from supersaturated vapor at temperatures below the triple point temperature.
In 1897 Ostwald formulated his step rule for formation of the most stable crystal state for a system with crystal polymorphism. The rule describes the irreversible way a system converts to the crystal with lowest free energy. But in fact the irreversible way a supercooled gas below the triple point temperature Ttr.p. crystallizes via a liquid droplet is an example of Ostwald's step rule. The ho...
متن کاملHydrostatic Pressure Correction Coefficient of the Triple Point Cell of Water
The hydrostatic pressure correction coefficient of the traditional triple point cell of water is determined from the measurements of temperature distribution along the thermometer well. The hydrostatic pressure coefficient obtained from these measurements is −0.855(30) mK/m, which is slightly different from the recommended value, −0.73 mK/m, of the International Temperature Scale of 1990. The l...
