Answer
Molecules move around fastest in the gaseous state. In gases, the molecules are far apart and possess high energy, allowing them to move freely and rapidly in all directions.

Answer
Molecules only vibrate about fixed positions in the solid state. In solids, molecules are closely packed and have limited movement, primarily oscillating around their equilibrium positions due to strong intermolecular forces.
