Quizplus · Accepted Answer

Stretching of a silver wire is a physical change as it does not involve a change in the chemical composition of the silver, only a change in its shape. Tarnishing of silver, on the other hand, is a chemical change as it involves the silver reacting with substances in its environment to form a new compound.
