c. Does not gain mass because matter cannot be created
Rusting is a chemical reaction in which the iron in the metal reacts with oxygen and moisture to form iron oxide (rust). While the appearance of the pipe may change due to the formation of rust, there is no creation of new matter during this process. Therefore, the pipe does not actually gain mass when it rusts.
Why does a pipe gain mass when it rusts? A. Matter is created during the chemical reaction b. Oxygen from the atmosphere bonded with the pipe to add mass to the pipe c. Does not gain mass because matter cannot be created d. It’s going through a physical chamge
