What is happening to the temperature of the substance BEFORE AND AFTER the phase changes?

First off, you must realize that the phase changes are marked by the points B and D on the graph. They are level because all of the energy (or heat) being added is being consumed by the physical process. So The temperature is increasing before the phase change, and after the phase change. The moments before and after are represented by points A, C, and E.

Before and after the phase changes or phase transition can be shown point A, B along with point E.

What is Phase transition?

Thermodynamics causes phase changes, which are transitions from one condition of matter to another. Melting and freezing are the processes through which solids and liquids change phases. Vaporization and condensation are liquid-to-gas phase transitions.

The temperature of a substance that has a first order phase transition stays constant over time as the phase change is incomplete. As ice at -10 degrees Celsius is heated, the temperature rises to 0 degrees Celsius. It begins to melt at that temperature, and solid water becomes liquid water.
