Is the glowing of a platinum wire in a flame a physical or chemical change?
It is a physical change. A physical change involves changing a substance only in its appearance, smell, taste, feel, or sound. A chemical change involves changing what makes up the substance or the way the substance reacts with other substances. When a normal platinum wire is placed over a flame, it glows. This is a physical change because the things that make up the platinum have not been changed, but the appearance has changed.
Is forming a bar of gold into wire a chemical change or a physical change?
This would be a physical change.
Is stretching copper into wire physical or chemical change?
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
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 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.
