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

relate this to kinetic energy?
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
