Determining the State of Carbon Dioxide Using the phase diagram for carbon dioxide shown in [link], determine the state of CO2 at the following temperatures and pressures: (a) −30 °C and 2000 kPa (b) −60 °C and 1000 kPa (c) −60 °C and 100 kPa (d) 20 °C and 1500 ...
Phase diagram is a graphic representation of the equilibrium relationships between phases (such as vapour-liquid, liquid-solid) of a chemical compound, mixture of compounds, or solution.

Phase diagram investigation of the Cu–Sn system was carried out on twenty Cu-rich samples by thermal analysis (DTA), metallographic methods (EPMA/SEM-EDX) and crystallographic analysis (powder XRD, high temperature powder XRD). One main issue in this work was to investigate the high temperature...
The maximum elongation reached in the model UFG phases before the beginning of global instability is marked with an asterisk. With full appreciation of excessively large values of strength a low \(q<0.5\) values, they are kept in the diagram for the visualisation of potential trends. For ...
First-principles swarm structure predictions are performed in an effort to seek for energetically stable and metallic selenium hydrides at high pressures. We find the phase diagram of selenium hydrides is rather different from its sulfur analogy, which is indicated by the emergence of new phases and...
\({V}_{{eq}}\) is derived from a simplified 1D graphite free energy model as described by Bazant’s group58,60, rather than from the two-layer model58, or various generalizations to 3 or more periodic layers, which are more accurate in modeling the phase diagram at different ...
(2019) studied the combined effect of several parameters such as surface roughness, wettability, solution chemistry, and the presence of water film on the dynamic contact angle. Through analysis of variance (ANOVA), they showed that the surface roughness and ionic strength affect the dynamic ...
