Is the metal tungsten used in incandescent light bulbs chemical property or physical property?
it is chemical property
Why do incandescent light bulbs waste a lot of energy?
Any form of electrical lighting will produce both light and heat, and with inefficient, incandescent lighting you get a higher proportion of heat rather than light, as compared to other forms of lighting such as fluorescent, or the most efficient, which is LED, which turns almost all of the electric power that it consumes into light, and very little into heat.
Do you use horse hair in light bulbs?
No horse hair in light bulbs. Today's incandescent light bulbs feature a tungsten filament. Since the filament must be heated to very high temperatures in order to glow, tungsten is the only fairly inexpensive metal with a high enough melting point to get the job done.
What element is a silvery white metal used in flare fireworks and photographic light bulbs?
Magnesium is a silvery white metal used in flares fireworks and photographic light bulbs
What is a light bulbs raw material?
Glass, metal, inert gas.
What metal is used in domestic lightbulbs?
The type of metal that is used in domestic light bulbs is known as tungsten. This is the metal that is usually found in incandescent light bulbs.
What is the metal in domestic light bulbs?
Tungsten in the filament of incandescent lightbulb.
What is the coil made of in incandescent light bulbs?
It is made of tungsten, a metal with a very high melting point.
Is the metal tungsten used in incandescent light bulbs chemical property or physical property?
it is chemical property
Why do incandescent light bulbs waste a lot of electricity?
Because they give off much of their energy as heat due to how the metal filament works
Do you use pig hair to make a light bulb?
No, pig hair is not used to make light bulbs. Light bulbs are typically made using a combination of glass, metal, and tungsten or other types of filaments. Pig hair is not a suitable material for this purpose.
Is a light of a flash light a ray of light?
Light is made up of light waves, which are different than normal waves because they do not need a medium, or a material to travel though. (Some examples of mediums are water, air, wood, metal...). Light waves come in different sizes, or wavelengths. Flashlights usually use incandescent light bulbs to produce light. Incandescent light bulbs produce light by heating a tungsten filament until it glows and gives off heat under the form of light waves.
What metal use the filaments in light bulbs?
Tungsten is used in filaments of light bulbs.
Why do incandescent light bulbs waste a lot of energy?

What is the difference between floroscent and incandescent?
Incandescent light bulbs contain a metal filament (normally tungsten). When electricity flows through the filament, it gets very hot, causing it to emit light. They are inefficient because most of the electric power goes into heat. Fluorescent light bulbs contain a circuit that increases the voltage of the electricity, which then ionizes mercury vapor. This ionized mercury emits ultraviolet light, which causes a coating on the inside of the glass bulb to glow ("fluoresce). They are more efficient, but many emit an ugly color of light.
Is krypton electrical insulator?
Incandescent light bulb"Light bulb" redirects here. For other types including compact fluorescent lamps, see Lamp (electrical component).An incandescent light bulbThe incandescent light bulb, incandescent lamp or incandescent light globe makes light by heating a metal filament wire to a high temperature until it glows. The hot filament is protected from air by a glass bulb that is filled with inert gas or evacuated. In a halogen lamp, a chemical process that returns metal to the filament prevents its evaporation. The light bulb is supplied with electrical current by feed-through terminals or wires embedded in the glass. Most bulbs are used in a socket (a housing giving mechanical support to the bulb, keeping its terminals in contact with the supply current terminals).
What are hair like filaments of fungi?
In an incandescent light bulb (the kind that screws into a standard light socket), the filament is the piece of metal in about the middle of the glass bulb that glows and emits light and heat when electricity passes through it. It is usually made of tungsten, but originally was made of carbon. New compact fluorescent and LED-based light bulbs do not really have filaments like incandescent light bulbs. Filament is a term also used in astronomy and biology for different things, but these uses are not as common as in light bulbs.
