I go over:
The definition of phase
The difference between solids, liquids, and gasses (the three phases) in terms of the kinetic theory of matter
The 6 types of phase change: fusion, freezing, vaporization, condensation, sublimation, and deposition
The melting point and boiling point
How potential energy is used to represent the strength of bonds between particles
Why potential energy is recorded as negative
Kinetic and potential energy in phase changes
How and why temperature does not change during a phase change
