The filament of an incandescent light bulb is actually significantly hotter than lava. Temperatures may exceed 4,000 degrees in some bulbs.

Is a light bulb a kind of lever?
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.
What do the support wires do on a light bulb?
As the name implies, support wires support the filament wire in the bulb, The filament, of course is the wire that glows white hot, giving out light
Why are electric light bulbs hot to the touch?
This is the case in any bulb that heats a filament. The current flowing through the filament generates heat which radiates photons and produces the light you see.
Why does a fused bulb not glow?
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
Does a light bulb get hot enough to melt a rubber band?
The bulb glows because the filament inside ( made of tungsten) get's so hot that it becomes red and starts emitting light. A little of it's heat is also radiated to the glass of the bulb and that's what makes it hot. But it will never get hot enough to melt a rubber band.
Which type of light bulb glows when a filament inside it gets hot?
An incandescent bulb.
Is a light bulb is a kind of lever?
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.

What is the part of a light bulb that gets hot and produces lights?
In an incandescent light bulb this is the filament. It is usually made of tungsten.

What part of a light bulb gives off electricity?
The part of an incandescent light bulb that gets hot and produces the light is called the filament.
Why does a light bulb filament glow?
The filament inside is heated. Once it gets hot enough, it dissipates some of the energy as heat and light.
Why do you need to have the glass on the outside of a light bulb?
The glass envelope, or bulb, of an incandescent light bulb is needed to hold the inert gas, such as argon, that fills the space. The filament of a light bulb is made of tungsten wire. When electricity passes through it the filament becomes extremely hot and emits light. The inert gas surrounding the filament protects it from evaporating too quickly. A light bulb only lasts as long as its filament lasts.
Does the filament of an incandescent light bulb glow because it gets extremely hot?
yes
How is resistance used to create light in a tungsten light bulb?
Electricity creates heat when flowing through a resistor such as the filament in a tungsten light bulb, and, since the heat can not be readily conducted away in the near vacuum inside a light bulb, the heat eventually raises the temperature of the filament to a value that leads to radiation of light from the hot filament.
