Is forming a bar of gold into wire a chemical change or a physical change?
This would be a physical change.
Is forming a bar of gold into wire a physical change or a chemical change?
Forming a bar of gold into wire is a physical change, not a chemical change. In this process, the gold undergoes a change in shape and physical state, but its chemical composition remains unchanged.
Forming a bar of gold into wire chemical or physical?
When a gold bar is shaped into a wire, the gold's chemical properties do not change. Only the physical appearance changes when gold is changed in shape. Thus, this is an example of a physical change.
Is Pouring molten gold in a mold a physical or chemical change?

If a gold ignot is hammered into gold leaf is this a physical or chemical change?
You are not changing the gold into anything else, so it is merely a physical change.

When gold changes from a solid to a liquid is that a physical or chemical change?
It is a physical change (melting).
Is hammering gold until it becomes flat a physical change or chemical change?
Pounding a gold coin into a different shape would probably not effect a chemical change. If, however, the pounding produced enough heat to meal the coin, some chemical change could take place.
Is making a ring out of a gold nugget a physical or chemical change?
There is no chemical change necessary to form a gold nugget into a ring.
Is panning a chemical change or physical change?
Panning (for gold) is neither of the above.
Physical or chemical hammering gold into a thin foil?
it's a physical change.
Gold is hammered into thin sheets physical or chemical change?
In a chemical change a substance undergoes a change in chemical composition. The appearance of the gold was changed in this case and not chemically combined with other elements to form new substances. Thus, this change is a physical change.
