20. HW Review (2 problems)

21. Cornell Notes: Heating Curve During a phase change you have a mix of the two phases. Phase Changes are flat because they occur at a constant temperature Potential Energy increases during phase changes Kinetic Energy increases when Temperature increases Time

22. Classwork p. 8

23. Classwork p. 8 Gas Liquid Solid

24. Classwork p. 8 Boiling Gas Liquid Melting Solid

25. Classwork p. 8 Phase Changes are flatbecause… Boiling Gas Liquid Melting Solid

26. Classwork p. 8 Phase changes are flat because there is no temperature change. Kinetic energy (the energy of movement) increases with temperature. Potential energy (energy from particle configuration) increases during melting and boiling.
