Explain why the potential energy increases when ice starts to melt and becomes liquid water.

My answer is, While the ice melts kinetic energy is being added to the particles. This breaks the bond and causes a change of state making the solid become a liquid.

Can you please check this over and give me some feedback

The molecules are pulled apart like stretching a spring.
