Uses of tungsten?
Tungsten's many alloys have numerous applications, most notably in incandescent light bulb filaments, X-ray tubes (as both the filament and target), and superalloys. Tungsten's hardness and high density give it military applications in penetrating projectiles. Tungsten compounds are most often used industrially as catalysts.
What is the general resistance of a tungsten filament?
The resistance of the filament in a light bulb is(voltage at which the bulb is designed to operate)2/(the rated power/watts of the bulb)
What is the difference between incandescent and fluorescent light bulbs?
Incandescent lightbulbs have an electrical circuit that passes through a tungsten wire. As the electricity flows, the tungsten is heated up to a point where it emits light waves. Gases (xenon, I think) help sustain the wire until it breaks. This is when the light stops and needs to be replaced. (the tungsten also emits heat when lit) Incandescent lights have the full spectrum of colors. Fluorescent bulbs are filled with a gas and a bit of mercury. Electricity gives the ions in the gas energy, which is released in the form of light. This method sustains the bulb far longer than an incandescent lightbulb. Fluorescents release much less heat, making them more energy efficient. However, the spectrum of the fluorescent bulb is missing a few colors of the spectrum, which makes the spectrum look cool and incredibly weird.A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor coating on the inside of the bulb to fluoresce (glow), producing visible light.
What is the most common and efficient route of exposure?
INHALATION
Is tungsten a metal?
yes
What element is used as a light bulb as a filament?
Usually tungsten.
Which element is used in light bulbs as filment?
Most often it is tungsten.
Which element is used in light bulbs as the filament?
Generally, tungsten.
What element is used a light bulb filaments?
Tungsten is the most common today.
Which is the most energy efficient light source?
LEDs are the most energy-efficient lights as of 2016.
Suggest the physical property that can render tungsten suitable for making filament of tungsten light bulb?
The physical property that can render tungsten suitable for making filament of tungsten light bulbs is incandescence.
What type of gas is in a tungsten-halogen light bulb?
Halogen gas is in a Tungsten-Halogen Light Bulb.
How do tungsten-halogen bulbs generate light?
Inside a tungsten-halogen bulb, electrons flow through a tungsten filament. The filament heats up and emits light.
A red fluorescent blu fluorescent or a tungsten-halogen light bulb would be most likely to cause a plant to wilt?
Tungsten halogen light because the graph shows that rapidly increases and doesn't go down
