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.
