No a light bulb does not use chemical energy. Even though it uses the chemical Mercury to create light. Hope this helps =)

As a chemist I can tell you that you have witnessed chemical energy being converted to light energy everytime you see a light bulb powered by a battery. The energy in the battery is stored as chemical energy, which is released by electrons leaving chemicals and flowing through the filament in the light bulb. As the electrons flow through the filament, they release some of their energy in the form of light. That is a rather simplified explanation, but if you want more detail, you better learn some indepth chemistry and physics first.
No.
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.
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.
No. The energy that goes into a light bulb is electrical energy, the energy that comes out is electromagnetic radiation, which we perceive as mostly heat and some light.
Using a light bulb.
Radiant (light) energy.
To convert electric energy into light energy

The job of a bulb is to convert electrical energy into light energy, a by product is heat energy.
The heat given off by a light bulb is thermal energy. The light itself is electromagnetic energy. All chemical energy is potential or stored energy.
The battery connected to the bulb has the potential chemical energy in it when it is connected by means of wire to the bulb the chemical energy in the battery is converted to the electrical energy which flows through the wire to the bulb glows the bulb which is a form of light energy after some time the bulb starts emitting heat which is heat energy.
Bulbs convert an electrical energy to produce light
Light bulbs convert energy to light. This conversion is inefficient, meaning that not all of the energy will convert to light because of the design of the bulb and the laws of physics. The energy that does not become light is released as heat, and that's why a light bulb gets hot.
Yes. The electromagnetic energy comes out of it in the form of light and heat.
Zero,because the distance has no affect to convert electric energy into light energy.
