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.
What else can I help you with?
Is turning a light bulb on a chemical change?
No.
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 turning on a light bulb on a physical or chemical change?
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 a light bulb a reversible change?
No, a light bulb is not a reversible change. When the filament inside the light bulb heats up and emits light, it undergoes a chemical change and cannot be easily reversed.
Is electric bulb glowing a example of chemical or physical changes?
The glowing of an electric bulb is an example of a physical change. When electricity flows through the filament of the bulb, it generates heat and light, causing the bulb to glow. This process does not involve any chemical reactions or changes in the composition of the materials in the bulb. It is simply a conversion of electrical energy into heat and light energy, which is a physical transformation.
Is a light bulb on a chemical or physical change?
Physical change
Is switching a light bulb on a physical or chemical change?
Physical change
Is turning a light bulb on a chemical change?
No.

Is turning on a light bulb on a physical or chemical change?
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 lighting a chemical or physical change?
Lighting is a physical change, not a chemical change. When a light switch is turned on, the flow of electricity through the bulb causes it to emit light, which is a physical reaction. No new substances are formed during this process.
Why the lightning of bulb not a chemical change?
The lightning of a bulb is a physical change because the transformation is reversible - the electricity passing through the filament causes it to heat up and emit light, but the filament itself remains the same material. A chemical change, on the other hand, involves a change in the chemical composition of the substance, which does not occur in this case.
Is a light bulb a reversible change?
No, a light bulb is not a reversible change. When the filament inside the light bulb heats up and emits light, it undergoes a chemical change and cannot be easily reversed.
Is a filament of a light bulb glows when an electric current flows through it is a chemical change?
It is a physical change brought about by the exitation of molecules producing heat and light. A general rule of thumb is that a physical change can be repeated on an article and chemical change cannot. Remove the current from a filament and it is still a filament.
Is electric bulb glowing a example of chemical or physical changes?
The glowing of an electric bulb is an example of a physical change. When electricity flows through the filament of the bulb, it generates heat and light, causing the bulb to glow. This process does not involve any chemical reactions or changes in the composition of the materials in the bulb. It is simply a conversion of electrical energy into heat and light energy, which is a physical transformation.
Is a lava lamp a physical change or a chemical change?
A lava lamp demonstrates a physical change. The wax inside the lamp changes states from solid to liquid due to the heat of the light bulb, but its chemical composition remains the same throughout the process.
Did a chemical change take place in a light bulb?
Possible oxidation of the metallic filament with traces of oxygen existing in the light bulb.
