What is the temperature of the tungsten wire when the incandescent bulb emits light?
Tungsten wire sublimation slowly thinning, the same time heat increases, the temperature will rise, so the last will be blown
When the incandescent lamp is lit, the temperature of the filament is above 3000 ° C. At this temperature, the other metal has long been melted into a liquid, or even become a gas, only tungsten can withstand.
Tungsten is the highest melting point of metal, its melting point up to 3410 ℃.
