The gaseous state of matter undergoes changes in volume most easily.

Explanation:

What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles.

This separation usually makes a colorless gas invisible to the human observer.

Since the molecules of a gas are so far apart, we can force them closer together by decreasing the volume.

We can also pull them away from each other by increasing the volume.
