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

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?

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
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?
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
