how is the kinetic energy of the particles of a substance affected during a phase change?\nkinetic energy increases during exothermic changes and decreases during endothermic changes.\nkinetic energy decreases during exothermic changes and increases during endothermic changes.\nkinetic energy does not change, but the potential energy does.\nkinetic energy changes in the opposite way that the potential energy changes.

Answer

Brief Explanations:

During a phase - change, the temperature remains constant. Since kinetic energy is related to temperature, the kinetic energy of the particles does not change. The energy involved in phase - change is used to change the potential energy (e.g., breaking or forming intermolecular forces).

Answer:

Kinetic energy does not change, but the potential energy does.
