What is an example of a physical change

Question

Rusting iron
Melting lead
Baking bread
Decaying wood

Answer 1

All of the examples you mentioned are actually chemical changes, not physical changes.

An example of a physical change is when water boils and turns into steam or when ice melts and turns into water. In both cases, the substance undergoes a change in its physical state without any alteration in its chemical composition.
