Answer:
The rearrangement of particles in a physical change
Step-by-step explanation:
Hello.
In this case, since phase transitions are physical changes in which the molecules of a substance in any phase rearrange in order to form another phase of the same substance, we can see that for gold when passing from liquid to solid, which is a process called freezing, the initial liquid gold has the particles not-so-close but also not-so-far to each other with a messy arrangement with lack of order as well but the final solid gold has a very organized network of particles, we can infer that the best statement describing such change is the rearrangement of particles in a physical change. You can verify the particles arrangement on the attached picture.
Best regards.
