Question

When liquid gold becomes a solid, its particles get closer together. Which best describes what happened to the gold?

A. the conservation of magnetism
B. the change in solubility in a physical change
C. the change in melting point in a physical change
D. the rearrangement of particles in a physical change

Answer 1

Answer: option D. The rearrangement of particles in a physical change.

Step-by-step explanation:

1) The change occured when a liquid substance becomes a solid is named freezing.

Yes, such as when liquid water becomes ice.

2) Such change is a change of phase or physical state of the matter. As such it is just a physical change: the chemical composition of the substance and the chemical bonds do not change.

3) At atomic or molecular level, what happens with the particles during freezing is that they come closer and are arranged in fixed positons one respect to the each other, so the particles do not slide over others. By occupying a fixed position, the substance acquires a definite shape and volume, and is not able to flow.

Answer 2

I believe the correct answer from the choices listed above is option D. When liquid gold becomes a solid, its particles get closer together. This happens due to the rearrangement of particles in a physical change. Hope this answers the question.
