Physics After long periods of use, a grey spot develops on the inside of a bulb. This is because Dust inside the bulb condenses on the top The heat of the bulb scorches the glass at the top The tungsten filament evaporates and collects there Glass undergoes a change due to the heat Dust inside the bulb condenses on the top The heat of the bulb scorches the glass at the top The tungsten filament evaporates and collects there Glass undergoes a change due to the heat ANSWER DOWNLOAD EXAMIANS APP
