Is a metal surface becomes dull because of continued abrasion a chemical or physical change?
Kthao5
Platinum rings acquire a dull satin finish from age and physical wear. Scratches do not actually remove metal from the ring but only displace the metal, so a platinum ring can be polished back to its original appearance without any wear to the ring.
