  40. 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

  41. Lab Post-Lab Questions: 1. What does the line look like on your graph when temperature is changing? 2. What does the line look like when temperature is not changing? 3.What does the first flat region represent? What does the second flat region represent?

  42. Lab Post-Lab Questions: 1. What does the line look like on your graph when temperature is changing? Goes up 2. What does the line look like when temperature is not changing? Flat 3.What does the first flat region represent? What does the second flat region represent? Melting, Boiling

  43. Lab 4. At times (flat regions of your graph), why does the temperature of a substance remain constant, even though energy is being added? 5. Label each segment of your graph, write which phase of matter is for each segment and for phase changes say what type of phase change is occurring (freezing, boiling, etc.) 6. During which phase were the water molecules the most free to move around? How could you tell? Can you relate this to kinetic energy?

  44. Lab 4. At times (flat regions of your graph), why does the temperature of a substance remain constant, even though energy is being added? Phase Change; heat is being used to increase potential energy by spreading molecules apart 5. Label each segment of your graph, write which phase of matter is for each segment and for phase changes say what type of phase change is occurring (freezing, boiling, etc.) 6. During which phase were the water molecules the most free to move around? How could you tell? Can you relate this to kinetic energy? Gas, because they leave the beaker! High movement = high kinetic energy

  45. Lab Boiling Gas Liquid Melting Solid

  46. Exit Ticket • You have an atom with 3 protons and 5 neutrons. Write it in isotope notation. • Classify apple juice as an element, compound, homogenous, or heterogeneous mixture and explain why. • What do the flat lines on a phase change diagram mean? Is the kinetic or potential energy changing? Explain
