Which state of matter is usually the least mobile?

Explanation:
Movement of particles varies by state. In a solid, particles are tightly packed in a fixed arrangement and held in place by strong forces, so they can only vibrate in place and don’t flow or diffuse. That makes solids the least mobile of the common states of matter. Liquids allow sliding past each other and flow, gases have particles that move freely and spread quickly, and plasmas are highly energetic ionized gases with rapid particle movement. So the solid state is the least mobile.
