Question

During an endothermic phase change, what happens to the potential energy and the kinetic energy?

Potential energy stays the same, and kinetic energy increases.

Potential energy increases, and kinetic energy increases.

Potential energy decreases, and kinetic energy decreases.

Potential energy increases, and kinetic energy stays the same.

Answer 1

Potential energy increases and kinetic energy stays the same.

Step-by-step explanation:

The balance between intermolecular forces (chemical potential energy) and kinetic energy determines phases. SO in endothermic phase change, since energy is released into the air, there is an increase in potential energy. During phase changes, the temperature does not change. Since there is no change in temperature, the kinetic energy also does not change.

I hope this makes sense :)

Answer 2

The correct answer should be that Potential energy increases, and kinetic energy increases, since they both increase as the temperature changes.
