The change of state that occurs when particles in a solid begin to move slowly past each other is called Melting.

During the melting process, as the temperature of a solid increases, the particles gain energy and overcome some of the forces holding them in fixed positions. This causes the solid to change into a liquid state, where the particles can move more freely, albeit still close to one another. Melting is a crucial phase transition in which a substance shifts from a solid phase to a liquid phase, allowing for greater particle mobility.

In summary, the correct answer is Melting.
