A gas surrounding a burning hot piece of metal in a sealed glass container, why dont they explode immediately?
In: Chemistry
IIRC icandescent bulbs were often partially vacuum-ized, so there was less gas inside than outside.
The filament would heat up any gas inside, yes, but that doesn’t mean it creates enough pressure to break glass. This is especially true if the regular pressure of the gas is less than the air outside, but could easily be true without that.
