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 glowing electric bulb physical or chemical change?
The glowing of an electric bulb is a physical change. This is because the light produced is a result of energy being converted into electromagnetic radiation, without any change in the chemical composition of the bulb's components.
Why is it heating a platinum wire in air is a physical change?
Heating a platinum wire in air is a physical change because it does not change the chemical composition of the platinum wire. The heat causes the platinum wire to expand and may change its physical appearance, but it remains chemically the same.
Is the luster of platinum jewelry a physical change?
Yes, the luster of platinum jewelry is a physical change. The luster is a result of the surface properties of the platinum metal, such as its reflection of light, without any alteration to the chemical composition of the metal.
When platinum is heated then cooled to its original state is a physical change?
Yes, heating platinum and cooling it back to its original state is a physical change. This process involves a change in the state of matter (from solid to liquid and back to solid) without altering the chemical composition of the platinum.
Is the luster of platinum jewelry physical or chemical property?
The luster of platinum jewelry is a physical property. Luster is a visual appearance attribute of the surface of a material, caused by the reflection of light. It is not a characteristic that involves a change in the chemical composition of the material.
Is melting platinum a chemical change?
No, it is a physical change.
Is glowing electric bulb physical or chemical change?
The glowing of an electric bulb is a physical change. This is because the light produced is a result of energy being converted into electromagnetic radiation, without any change in the chemical composition of the bulb's components.
Is a glowing neon sign a physical change?
Yes, a glowing neon sign represents a physical change because the neon gas inside the sign undergoes a change in energy state to emit light. This change is reversible and does not alter the chemical composition of the neon gas.
Is a platinum ring becoming dull because of continued abrasion a physical or chemical change?
It is a physical process.

Are glow sticks glowing a chemical change?
Yes, the glowing of glow sticks is a chemical change. It results from a chemical reaction between the chemicals inside the stick when they are mixed, producing light as a byproduct.
Is stapling an envelope a physical change or chemical?
