Which state of matter has the greatest amount of particle movement?

The state of matter that has the most energy is gas.

Explanation:

In a solid, there is limited room for molecules to move around.

The greatest amount of particle movement is in gaseous state of matter.

Explanation:

It is known that matter can be classified as solid, liquid and gas states. The molecules in each state exhibit vibrations or movement of particles will be occurring in them. The kinetic energy exhibited by the different states of matter depend upon the bond strength.

If the bond strength is more and if the particles are densely packed like in solids. So the gas state has least bond strength and they are loosely packed molecules and thus the particles can move freely with more kinetic energy.
