Understanding Reversible Changes

1. Definition of Physical Change: Physical changes involve a change in physical properties without altering the chemical composition of a substance. Examples include melting, freezing, or dissolving.

2. Definition of Chemical Change: Chemical changes involve a transformation that alters the chemical composition of the substance, often resulting in the formation of new substances. Examples include rusting, combustion, or digestion.

3. Reversibility:

   • Physical changes are generally reversible. For instance, when water freezes into ice, it can be melted back into water.
   • Chemical changes are usually not reversible easily or may require specific conditions.

Conclusion

Based on the definitions and characteristics discussed, the answer to the question is that physical changes are the changes that can be easily reversed. Therefore, the correct answer is:

Physical change.
