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.
No physical change occur.
Bioluminescence is a chemical process.
Chemical broooooooooooooooo niga
it is a chemical change
Chemical I think
physical as the chemical structure does not change.
It is a physical change. When you supply electricity, the electrons jump to higher energy state. When they come back to their level, it emits energy which falls in the visible region of light. The atoms of the filament (Tungsten) are not going through any change, that changes their chemical properties. Tungsten, still remains tungsten!
No, it is a physical change.
It is a physical process.
No, a metal bar glowing red hot in a fire would be an example of a physical change, not a chemical change.
