Example of produce gas in physical change?
A piece of metal that is heated will expand and produce gas due to the reaction of the metal with oxygen in the air, forming metal oxides. This is a physical change because the metal itself does not change its chemical composition, but it does result in the production of gas as one of its observable effects.

Is metal corroding a physical change or chemical change?
Corrosion is a chemical change
Does metal expand when heated or cooled?
No. A chemical change occurs only when a new substance is produced with new and different properties. In your example, a physical change occurred because only the metal's physical properties were affected. Nothing new was created.
