Question

All of the following changes to a metal are physical changes EXCEPT _______.

A. Bending
B. Polishing C. Cutting
D. Rusting
E. Melting

Answer 1

Physical changes such as bending, polishing, cutting, and melting do not involve a change in the chemical composition of the metal. However, rusting is a chemical change that involves a reaction between iron and oxygen, resulting in the formation of iron oxide.

Step-by-step explanation:

All of the changes mentioned are physical changes except for rusting. Bending, polishing, cutting, and melting are all physical changes because they do not involve a change in the chemical composition of the metal. However, rusting involves a chemical reaction between iron and oxygen, resulting in the formation of iron oxide. This is a chemical change because the composition of the metal is altered.
