It is a chemical change but it can be reversed since that cahnge is only on the surface. It is merely an oxidization that occurs when silver is exposed to oxygen and has no contact with oil (which blocks the pores of the metal from reacting with oxygen).
That is a chemical change in which the silver is reacting to the oxygen in the air and is tarnishing.
This is the result of the silver reacting with the oxygen in the air.

If a silver colored ring turns your finger green it is a physical change that is caused by a chemical reaction.
Color is a physical property, not a change.
It's a chemical change. The silver reacts with sulfur compounds from the air.
physical, because in order for a chemical change to take place, the object must become something new. Silver is still silver if it is bent.
The change in the state of matter between solid, liquid and gas are not chemical changes. The melting point of a substance, silver in this case, is a physical characteristic.
