The example that demonstrates the reversibility of a chemical change from the options provided is:

refreezing carbon dioxide gas into dry ice.

Dry ice is solid carbon dioxide, which can change back to gas when it sublimates, and this process does not involve a chemical change. The other options involve irreversible changes or reactions.
