Is electric bulb glowing a example of chemical or physical changes?
It is a physical change. When you supply electricity, the electrons jump to higher energy state. When they come back to their level, it emits energy which falls in the visible region of light. The atoms of the filament (Tungsten) are not going through any change, that changes their chemical properties. Tungsten, still remains tungsten!
What items contain tungsten?
Electric bulb Filament
What element is used for a filament for light bulbs?
Tungsten
Why are V-i characterstics different for tungsten and carbon lamp?
As carbon filament bulbs have a negative temperature coefficient and tungsten filament light bulbs have a positive temperature coefficient.
What element is used in a light bulb as a filament?
Usually tungsten.
What property does tungsten have that make it suitable for making filament?
the reason that tungsten is better then carbon for light filaments is because the melting point is higher,. the melting point of carbon is only 3550, as where tungstens melting point is 3695
Is tungsten a physical or chemical property?
Tungsten (wolfram, W) ia chemical element, not a property.
Physical property of tungsten?
Tungsten, W, with the highest melting point of all elements: 3680 K
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.
Which material is used for for filament in tungsten lamp?
i believe it is cadnium.
What is in filament of light bulbs?
tungsten
Light bulb filament?
What is Tungsten
What is the property of the filament that makes it light up when electricity flows through?
the simple answer is resistance, the filament is a very fine wire (usually tungsten) that heats up and glows when power is applied

Why do lightbulbs burn out?
They burn out from 1) the rapid heating and cooling of the Tungsten filament, and 2) from the tungsten atoms being released from the metal filament by way of the extremely high temperatures. Eventually the tungsten metal fails and the filament breaks.
Is the metal tungsten used in incandescent light bulbs chemical property or physical property?
it is chemical property
