Answer:
In the process, the rearrangement of particles taking place in the gold signify a physical change.
Step-by-step explanation:
A physical change refers to the one that modifies the form of a substance, however, it does not influence its composition. When liquid gold turns solid and its constituents come close to each other, it shows a physical change as in the given case, the liquid state is transformed into a solid-state and there is not influence taking place on the composition of gold.
Further, in comparison to the liquid state, in solid-state, the particles come close to each other. Therefore, the rearrangement of particles in a physical change best illustrates the liquid gold turning solid and its particles getting close together.
