No. Heat and light are forms of energy, not matter.
When a fluorescent lamp is turned on, the electricity excites the mercury vapor inside the tube. UV light is produced. The UV light excites the phosphor coating. The phosphorus atoms relax by releasing a visible light. Since the light emitted by the phosphorus atoms is of a spread spectrum (the frequency is not fixed), the light appears whitish. To summarize, electricity is turned into light.
Well.. the difference is that fluorescent light isn't natural and natural light isn't fluorescent . its not rocket science (:
light bulb
That varies, depending on the technology. In an incandescent light bulb, a wire is heated when electricity passes through it, until it glows. In a fluorescent light bulb, atoms in a gas get into an excited state, and emit light when the electrons fall back to their normal energy level.
is gas, liquid, or plasmaBut I need only one.plasma
when a fluorescent light bulb is turned on, the state in it is still gaseous state. no change of state occurs by turning it on. It functions like a CRO(search cathode ray oscilloscope). one end acts as a cathode and the other as an anode. electron beam is produced by the cathode and it moves toward the anode. on thier way to anode, electrons collide with the walls of the glass. on the inside of the glass, it is coated with such a material that when electron collides with that surface, it produces a small flash of light. when millions of electrons do that, we see a bulb turned on.

Fluorescent or compact fluorescent light fixtures are the most efficient in terms of energy costs. The placement of the fixtures does not matter greatly as long as the light is not blocked and is reasonably centrally located, with additional lighting for the mirror/vanity.
It produces light
yes
Anything that excites the gas in a fluorescent will make it light. Static electricity from the carpet will cause compact fluorescent to light.
A plasma screen TV, the northern lights, and fluorescent light bulbs.
