Any substance that dissociates into ions in water, such as salt (sodium chloride), will cause the light in a conductivity apparatus to glow. This is because the dissociated ions in the solution can conduct electricity, allowing the light to illuminate.
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.
The atmosphere of the earth.
Evaporated human urine can glow in the dark due to the presence of phosphorus compounds such as phosphates. These compounds can become luminescent when exposed to ultraviolet light sources. The glow is known as fluorescence and is a common property of certain chemical compounds.
Heat lightning refers to the faint flashes of light seen on warm, humid nights, typically without accompanying thunder. It is caused by distant thunderstorms, where the lightning is too far away for the sound of thunder to be heard. The phenomenon often appears as a glow on the horizon, illuminating the clouds. Essentially, heat lightning matches the occurrence of lightning from storms that are beyond the observer's range of hearing.
fireflies glow bacause of a chemical in it's body
Lightning is a burst of electricity caused by the discharge of built-up static electricity in the atmosphere. It produces light due to the intense heat generated by the electrical discharge, which causes the surrounding air to glow. So, it is a combination of both electricity and light.
yes and sometimes they even glow because of lightning inside of them!
i think they are because my teacher thinks they are but we're not for sure.
glow worms, lightning bugs, and mcdonalds. hope this helped.
A fluorescent light uses electricity to create ultraviolet light in a tube filled with mercury vapor and a phosphor coating. The ultraviolet light interacts with the phosphor coating, causing it to emit visible light, which is what makes the fluorescent light glow.
Incandescence. The filament is heated by the electricity moving through it, this causes the filament to heat up, and the heat causes the familiar glow.
lightning bugs, glow worms, or luciérnaga
if you eat enough of them you will praly get constipated and your stomach would glow...... true story
Electricity through a thin wire (filament) makes it glow, which is prevented from burning through the wire by gas inside the bulb.
Electricity is not kept in a light bulb because there is nowhere to put it... It is not like a battery! Maybe, because they knew a light bulb can't keep any electricity, that is why your Mom and Dad thought your question was dumb? Well, it is not really all that dumb, it just had one word in it that was wrong. No question is dumb if it is asking asking how something works because that is always a good thing to do. That's the best way to learn about things! What we can say to answer your question is: Electricity is used up or consumed by a light bulb. The electricity it uses up makes it glow so brightly that it sends out light which we can see. When a light bulb is switched off it is said to go out, which just means it is not glowing any more. It can't glow when it is switched off because no electricity can get into it through the switch. That is why we say we have to switch on a light bulb, using a switch, to give it enough electricity to glow and give out light.
An electric light bulb converts electrical energy into thermal energy which is in the form of radiated light and heat. For example, the " easy bake oven" uses a light bulb to cook the food.
