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.
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 chemical change or a physical change?
Forming a bar of gold into wire is considered a physical change. This is because the gold's chemical composition remains the same during the process, only its physical shape is altered.
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.
Is forming a bar of gold into wire a physical change or a chemical change?
Still a physical change because its still gold and weren't doing anything like making a new element or mixing chemicals with the gold. So its still a physical change.
What is the evidence that indicates that only physical changes occur when a platinum wire is heated in a Bunsen burner flame?
The evidence that indicates only physical changes occur when a platinum wire is heated in a Bunsen burner flame includes the fact that the platinum wire does not combine with oxygen or any other element in the flame to form a new substance, and the wire retains its chemical properties after cooling down. The color change of the wire due to heating is a reversible physical change, and the wire can be restored to its original state without any alteration in its composition.

Is twisting a wire chemical or physical change explain?
It is physical. The wire changes shape, but it is still made of the same materials.
Is stretching wire into copper a physical or chemical change?
Stretching wire into copper is a physical change because the composition of the material remains the same. The rearrangement of copper atoms in the wire does not alter the chemical identity of the substance.
Is a bending a metal wire a physical change?
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
Is bending a metal wire a chemial or phyiscal change?
Physical. The metal wire is still a metal wire after the change.
Is heating a chocolate chemical change?
Yes, burning of a sparkle is a chemical change because once sparkle has changed its form it cannot come into its previous form. For understanding you can also take the example of cooked rice which once cooked cannot be raw again.

Is the tranishing of silver chemical or physical change?
Drawing it into a wire is a physical change of silver.
