11.7: Phase Diagrams
The Phase Diagram of Carbon Dioxide. In contrast to the phase diagram of water, the phase diagram of CO 2 (Figure 11.7.3 ) has a more typical melting curve, sloping up and to the right.The triple point is −56.6°C and 5.11 atm, which means that liquid CO 2 cannot exist at pressures lower than 5.11 atm. At 1 atm, therefore, solid CO 2 sublimes …
Phase Diagrams: The Beginning of Wisdom
The boundary line between the BCC (α) and FCC regions is defined by the equality of the Gibbs energy values, G BCC (T, P) = G FCC (T, P).That line not only reveals the pressure dependence of the BCC (α)/FCC phase transformation temperature, but also forms the two-phase region BCC (α) + FCC in the phase diagram. All these two-phase …

Three-dimensional phase change diagrams plot three thermodynamic variables and show regions of space corresponding to different phases. In this type of diagram, we have a triple line instead of a triple point, and coexistence surfaces instead of coexistence curves. Below is a generic 3D diagram plotting temperature, pressure, and specific volume.

A phase diagram is a graph which the conditions of temperature and pressure under which a substance exists in the solid, liquid, and gas. The triple point is the one condition of temperature and pressure where the solid, liquid, and vapor states of a substance can all coexist at equilibrium.
Phase Diagram: Definition, Explanation, and Diagram
Phase Diagram. A phase diagram represents the various physical states or phases of matter at different pressures and temperatures. In other words, it summarizes the effect of pressure and temperature on the nature of a substance. A phase diagram is divided into three areas representing the substances' solid, liquid, and gaseous phases [1-4].

What Is a Phase Diagram?
Typically, a phase diagram includes lines of equilibrium or phase boundaries. On these lines, multiple phases of matter can exist at equilibrium. The lines also indicate where phase transition occur. Triple points occur where lines of equilibrium intersect. A triple point identifies the condition at which three phases of matter can coexist.
