HW Review (2 problems)
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

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.
