I think it is physical but I do know it is an igneous rock
The change in the state of matter between solid, liquid and gas are not chemical changes. The melting point of a substance, silver in this case, is a physical characteristic.

Their reaction with the water is a purely chemical change, however the chemical reaction is so intense and violent that it is usually followed by many dangerous physical changes (e.g. boiling of the water, flinging molten pieces of the unreacted metal at you, spattering drops of lye solution at you).

Yes. Gold would have to bond with something for it to be a chemical change.
Melting iron is a strictly physical change (change of state). The molten and solid iron would be identical by any chemical test or reaction.

A physical change; you're turning the solid glass into a semi-liquid molten state, forming it into a desired shape, and then allowing it to cool and harden.

Anything else then dropping it in molten gold is chemical
