Chem 110 - Class Guide: Phase Changes, Vapor Pressure and Phase Diagrams Chapter 11, SecTons 4-6 Learning Goals: Upon completon ChapTer 11, Sectons 4 - 6, you should be able To: Sketch a heatng/cooling curve for a represenTatve subsTance, showing how The TemperaTure of a subsTance is aFecTed by heaT change. Calculate The enThalpy change for a subsTance using enThalpies of fusion, vaporizaton, or sublimaton, and The heatng/cooling curve. Categorize molecules wiTh respecT To Their relatve vapor pressures and normal boiling poinTs using knowledge of Their inTermolecular forces. Sketch a phase diagram for a subsTance, including The Triple poinT and The critcal poinT. State how The phase diagram for waTer diFers from mosT subsTances. Chapter Reading Guide: Chapter 11, SecTons 4-6 SecTon 4: PHASE CHANGES When a gas becomes a liquid, or vice versa, The subsTance goes Through a phase change . ±he same Thing happens when a solid becomes a liquid, or a liquid becomes a solid. ±he energy required To melT a subsTance is called The heat of fusion , ∆H fus.
