Answer 2

Answer:

Physical changes are reversible and do not result in the formation of a new material. Chemical reactions produce a new material that cannot be reversed.

Explanation:

• All physical changes involving a change of state are reversible. Other state transitions include vaporisation (from liquid to gas), freezing (from liquid to solid), and condensation (gas to liquid).
• Dissolving is also a physical change that can be reversed.
