A gas surrounding a burning hot piece of metal in a sealed glass container, why dont they explode immediately?
In: Chemistry
They do!
Or, they used to.
But, home voltages are much more controlled than they used to be, manufacturing defects happen much less often than they used to, and most bulbs sold today do not have a strip of tungsten heated to hundreds of degrees in a sealed vacuum.
The “sealed vacuum” bit above is why they didn’t just explode randomly all the time before. Explosions require fuel, like oxygen, and there isn’t any in a properly sealed bulb.
