What would indicate that a physical change takes place when copper is drawn into wire

Explanation:

A physical change is defined as a change that does not bring any difference in chemical composition of a substance.

For example, shape, size, mass, volume, density, etc of a substance are all physical properties.

So, when copper is drawn into wire then there will occur change in its shape but there will not be any change in its chemical composition.

Whereas when a change in chemical composition of a substance occurs then it is known as a chemical change.

Hence, we can conclude that change in the shape of copper when it is drawn into wire indicates a physical change.
