Heating & Cooling Curves - Phase Change Diagrams - (Temp vs Time/Energy Graphs)

• Kinetic Energy (Vibrations) - Increases whenever the temperature increases
• Potential Energy - Increases when the temperature is NOT increasing (during the phase change)
• Temperature DOES NOT CHANGE during a phase change. The energy goes into pulling apart atoms/molecules to weaken and overcome the intermolecular forces.
