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

Physics On a cold day when a room temperature is 15oC, the metallic cap of a pen becomes much colder than its plastic body, though both are at the same temperature of 15oC, because metals are good conductor of heat plastics have a higher thermal conductivity than metals plastics have a lower density than metals metals have higher thermal capacity than plastics metals are good conductor of heat plastics have a higher thermal conductivity than metals plastics have a lower density than metals metals have higher thermal capacity than plastics ANSWER DOWNLOAD EXAMIANS APP
