usually Nitrogen.
A fluorescent bulb emits a line spectrum, primarily due to the excitation of gas molecules inside the bulb. When electricity passes through the gas, it excites the atoms, causing them to emit light at specific wavelengths characteristic of the gas used, typically mercury vapor. This results in distinct lines of color rather than a continuous spectrum, which is then converted to visible light by the phosphor coating on the inside of the bulb.
When you burn a light bulb, the heat generated can cause the filament inside an incandescent bulb to melt and break, leading to the bulb's failure. In fluorescent bulbs, the gas inside can become unstable and release toxic substances. Additionally, the glass can shatter due to the intense heat, posing a safety risk. Overall, burning a light bulb is dangerous and can create hazardous conditions.
Light bulb is filled with inert gas or simply a vacuum.
A typical fluorescent light bulb operates on a voltage range of about 100 to 250 volts, depending on the specific type and design. The bulb requires a ballast to regulate the current and voltage for proper operation. However, when considering the voltage across the electrodes inside the bulb during operation, it can be around 1,000 volts due to the ionization of the gas inside.

The presence of gas inside a light bulb affects its performance and longevity by influencing the efficiency of the bulb. The gas helps prevent the filament from evaporating too quickly, which can extend the bulb's lifespan. Additionally, the type of gas used can impact the color and brightness of the light produced.
A fluorescent light bulb produces light when electricity passes through a gas or vapor, typically mercury vapor, inside the bulb. This process produces ultraviolet light, which then causes the phosphor coating on the inside of the bulb to fluoresce, emitting visible light. So, in this case, the state of matter involved is gas or vapor inside the bulb.
The globe is the outer glass shell. The shaped coil inside is the filament. Wires and the stem support the filament inside the bulb. There are gases within the light bulb to prevent it from burning out. And the base is to securely support the bulb.
Argon gas is commonly used inside incandescent light bulbs to prevent the filament from oxidizing and burning out. It helps to prolong the life of the bulb by reducing the evaporation of the filament material.
No. The light bulb is two words, not a combination of light and bulb.
A fluorescent light bulb produces light by exciting the gas inside it, usually mercury vapor or neon. The excited gas atoms emit ultraviolet light, which stimulates a phosphor coating on the inside of the bulb to produce visible light. So, when a fluorescent light bulb is turned on, it emits light through a process involving excited gas and phosphor.
There are several types of light bulb. A basic incandescent bulb will contain a tungsten filament, surrounded by a vacuum. Variations may have an inert gas inside the bulb, such as halogen.
Tungsten and an inert gas can be found inside of a light bulb.
The gas in a light bulb is Argon
The gas typically present inside an incandescent light bulb is nitrogen or a mixture of nitrogen and argon. This gas helps prevent the tungsten filament from burning up by reducing the rate of evaporation.
The swirly light bulb is called a compact fluorescent lamp (CFL). It is a type of energy-efficient light bulb that produces light by using electricity to excite the gas inside the bulb to create illumination.
A fluorescent light bulb contains a gas which produces UV light when it comes in contact with electricity. Contrary to a normal light bulb this does not create any heat and is far more energy efficient.
