## Educational Text on Phase Diagrams ### Phase Diagram Exploration #### Questions and Answers 4. **Using the phase diagram to the right:** a. **Label each phase** in the diagram to the right in the box provided. b. **What is the normal melting and normal boiling points?** c. **What is the phase change associated with letter A** when the pressure is suddenly dropped? d. **What singular change can you do to letter B to vaporize it?** e. **What is happening on the molecular level** for your answer in part D to work? f. **What is the vapor pressure of this substance at approximately 80K?** ### Diagram Description - The phase diagram is a graph showing Temperature (T) on the x-axis in Kelvin and Pressure (P) on the y-axis in atm. - It includes three regions labeled with lettered boxes A and B, indicating phases of matter. - The lines in the diagram represent the boundaries between different states (solid, liquid, and gas). ### Key Observations - The diagram includes critical points and the slope of the lines distinguishes between phase changes like melting, boiling, etc. - Specific temperatures and pressures where transitions occur are marked on the graph. This educational content is aimed at understanding how phase diagrams work and interpreting them to determine phase changes and properties related to different substances.
