An incandescent bulb.
In an incandescent light bulb this is the filament. It is usually made of tungsten.
Depends how long you leave it on for....
yes
Light bulbs convert energy to light. This conversion is inefficient, meaning that not all of the energy will convert to light because of the design of the bulb and the laws of physics. The energy that does not become light is released as heat, and that's why a light bulb gets hot.
You can't get a wart from a hot light bulb.
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.

light bulbs are hot because the coils spread heat around the bulb.
In simple terms, the current passes through the tungsten filament present in the bulb which causes it to heat instantaneously into red hot to white hot and hence light energy emits.
yes
Lightbulbs do get hot when lit - even cfl bulbs get a bit hot.
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.
