Physics After long periods of use, a grey spot develops on the inside of a bulb. This is because 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 Dust inside the bulb condenses on the top The heat of the bulb scorches the glass at the top ANSWER DOWNLOAD EXAMIANS APP
Physics Mud houses are cooler in summers and warmer in winters as compared to brick houses because Mud is a bad conductor Mud is a poor insulator Mud is a good conductor Evaporation of water causes cooling in summers and sunlight coming through holes causes warming in winters Mud is a bad conductor Mud is a poor insulator Mud is a good conductor Evaporation of water causes cooling in summers and sunlight coming through holes causes warming in winters ANSWER DOWNLOAD EXAMIANS APP
