Example of a Heating Curve for a Substance**To analyze as a cooling curve, read the below heating curve in reverse starting at segment E and ending at segment A**For any phase change that overcomes intermolecular forces to move the molecules apart, potential energy increases while kinetic energy remains constant. Phase changes that fit this description include: Fusion, vaporization and sublimation.For any phase change that must require a cooling that allows molecules to move together another and strengthen intermolecular forces, potential energy decreases while kinetic energy remains constant. Phase changes that fit this description include: Solidification, condensation and deposition.
