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

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?

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
