Final answer:

Reversible changes, like melting ice, can be undone by reversing the process, making them reversible physical changes.


Explanation:

Reversible change: Melting ice is a reversible physical change as the melted ice can be refrozen. Other changes of state like vaporization, freezing, and condensation are also reversible. Dissolving salt in water and then regaining the salt by boiling off the water is an example of a reversible change.
