During a phase change, the temperature stays the same. Here's a step-by-step explanation:

1. When a substance is heated, its temperature rises as it absorbs heat energy.

2. However, when it reaches the temperature at which it changes phase (for example, the boiling point for a transition from liquid to gas), the temperature stops increasing.

3. All the heat energy being absorbed by the substance is used for the phase change. This is because the energy is used to break the bonds between the particles in the substance, rather than to increase the kinetic energy of the particles (which would raise the temperature).

4. Once the phase change is complete, the temperature of the substance will start to rise again if more heat is added.

So, during a phase change, the temperature of a substance remains constant.
