Question

when liquid gold becomes a solid, its particles get closer together. which best describes what happened to the gold?
○ the conservation of magnetism
○ the change in solubility in a physical change
○ the change in melting point in a physical change
○ the rearrangement of particles in a physical change

Explanation:

Liquid gold turning solid is a physical change (no new substance forms). The question states particles move closer, which is a rearrangement of particles. The other options are irrelevant: magnetism, solubility, and melting point change are not described here.

Answer:

the rearrangement of particles in a physical change
