The reason why turning on a light bulb is a physical change is because there is a process of electrical energy being converted into light and heat. You still have the light bulb intact and no new substance is formed.

Is turning glow sticks on a chemical or physical change?

Turning on a glow stick is a chemical change because the chemicals inside the stick react to produce light. This reaction cannot be easily reversed, unlike physical changes where the substance retains its original properties.


Is a light bulb a chemical or physical change?

A light bulb is not a change in and of itself but the process by which it gives off light is physical. While an electric current causes a given component of the bulb to glow (it may be the filament of an incandescent bulb or the vapor in a fluorescent one), but that substance does not change its chemical identity.


Is emission of light a chemical or physical change?

Most of the time the emission of light is a physical change but there are some chemical reactions which emit light as a byproduct of the reaction.

Is flash cameras flashing a chemical or physical change?

The flash of a camera is a physical change, not a chemical change. A physical change is a change in the form of a substance without changing its chemical composition. In the case of a camera flash, electrical energy is converted into light energy, which is a physical process that does not alter the chemical makeup of the components involved.

Is heat light and change in odor indicate a physical change?

Heat, light, and change in odor can indicate a physical change depending on the context. For example, melting ice into water is a physical change because it does not alter the chemical composition of the substance. However, if a substance undergoes a chemical reaction that results in heat, light, and change in odor, then it would be considered a chemical change.


Is the generation of light by an electric lamp a chemical or physical change?

This is a physical change. When the electrons go through the filament (or gas), there is no chemical change, only the physical change of temperature. The electricity to power the light may be generated chemically (fossil fuels or batteries) or from a hydroelectric plant. The light from "glow sticks" is an example of light generated by chemical changes.
