Question

What happens to the potential energy along the horizontal axis from right to left at part II on the heating curve?

Answer 1

In part II of the heating curve, the potential energy remains constant along the horizontal axis.

Step-by-step explanation:

In part II of the heating curve, the potential energy remains constant along the horizontal axis from right to left. This is because during this phase, a substance is undergoing a phase change where the temperature remains constant. At this point, the energy is being used to break the intermolecular forces and convert the substance from one phase to another.
