AGas, liquid, solid
BLiquid, plasma, solid
CLiquid, gas, plasma
DPlasma, gas, solid
Answer & Solution
Correct answer: C. Liquid, gas, plasma
1. In a solid, particles vibrate but keep the same neighbors and cannot change position with them.
2. In a liquid, particles can slide past one another and change neighbors freely.
3. In a gas, particles are separated by large distances and move independently, changing position constantly.
4. Plasma particles are even more free than gas particles, since they are ionized and unbound.
5. So liquid, gas, and plasma are the phases where particles change position, while solid is the exception.
