Ex:
Interpret a heating curve
When temperature is constant (or the slope = 0), there is a phase change occurring. When temperature is increasing, there is no change.
Interpret a cooling curve
When temperature is constant (or the slope = 0), a phase change is occurring. When temperature is decreasing, a phase is cooling and there is no change.
Interpret energy exchange graphs
During a phase change, energy is always exchanged between the system and surroundings.
