Summary
This document presents a phase diagram for carbon dioxide, visually representing the different phases (solid, liquid, gas) and the transitions between them. It details how temperature and pressure influence the phases and explains related concepts such as the triple point and supercritical fluid. This would be suitable and interesting for students learning about phase changes and properties of substances.

CARBON DIOXIDE PHASE DIAGRAM Phase Diagrams Major Phases = Solid, Liquid and Gas A phase diagram is a graphical representation of the different phases of a substance which exist at different temperatures and pressures. Temperature is on the x axis and pressure is on the y axis of the graph. The different regions of the diagram correspond to the different phases. Low pressure and High temperature = Gas High pressure and Low temperature = Solid High pressure and High temperature = Liquid The lines in a phase diagram correspond to the different phase changes. These are called the Sublimation, Fusion, and Vaporization lines. Supercritical Fluid: An ambiguous phase with properties of liquids and gases. I A substance is in a supercritical state when the applied pressure is > the critical pressure (Pc) and the applied temperature is > the critical temperature (Tc). The critical point is at the end of the vaporization line. Triple point: The convergence of the sublimation, fusion, and vaporization lines. All three phases exist at the same time under at a specific triple point pressure (PTP) and triple point temperature (TTP). Normal Boiling Point: The temperature at which the Liquid/Gas phase transition occurs at 1 atm. Normal Freezing Point: The temperature at which the Solid/Liquid phase transition occurs at 1 atm. Normal Sublimation Point: The temperature at which the Solid/Gas phase transition occurs at 1 atm.
