Calculate Heat energy released or added during a phase change. 10. Qualitatively interpret heating curves in terms of changes in kinetic and potential energy of molecules, heat of vaporization, heat of fusion, and phase changes. 11. Explain Phase Changes in terms of the changes in energy and intermolecular distances. 12. Convert between temperatures (Celsius, Kelvin, Fahrenheit)
