Final answer:
The indication of a physical action among the provided options is peeling or discoloration of a container's finish, which reflects a change in physical appearance without a chemical composition change. The correct option is D.Peeling or discoloration of a containers finish
Step-by-step explanation:
Among the options provided, the indication of a physical action would be peeling or discoloration of a container's finish. This change is associated with the physical appearance and does not involve a change in the chemical composition of the substance, hence it's a physical change.
Some examples to illustrate this concept are:
- Ice melting: Water changes from solid to liquid form but remains H2O.
- Boiling water: Water changes from liquid to gaseous form, but its chemical composition does not change.
- A mirror being broken: The glass is physically broken into pieces without altering its chemical structure.
Chemical changes, on the other hand, involve a substance changing into a different substance with a different chemical composition, such as:
- A nail rusting: Iron reacts with oxygen to form iron oxide, which is a chemical change.
- Burning of gasoline: Combustion converts gasoline into carbon dioxide and water, a new chemical makeup.
The correct option is D.Peeling or discoloration of a containers finish
