when liquid gold becomes a solid, its particles get closer together. which best describes what happened to the gold?\n○ the conservation of magnetism\n○ the change in solubility in a physical change\n○ the change in melting point in a physical change\n○ the rearrangement of particles in a physical change
Answer
Brief Explanations:
- Conservation of magnetism: Gold is not magnetic, and this concept is not relevant to the phase change from liquid to solid.
- Change in solubility: Solubility refers to a substance's ability to dissolve in a solvent. This is not related to the phase change of gold from liquid to solid.
- Change in melting point: The melting point is a characteristic property of a substance and does not change during a phase change. The phase change (liquid to solid) is a result of temperature change relative to the melting point, not a change in the melting point itself.
- Rearrangement of particles in a physical change: In a physical change (like freezing, which is what happens when liquid gold becomes solid), the chemical composition of the substance remains the same. The particles rearrange themselves. In the liquid state, particles have more freedom of movement and are relatively farther apart compared to the solid state where they are more closely packed and have a more ordered arrangement.
Answer:
the rearrangement of particles in a physical change
