Chemical change (which results in physical change).
Is melting copper an example of chemical change?
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
Is melting copper with tin to form bronze chemical change?
