why rooms are provide with ventilator?
Answer:
Ventilators are provided in rooms for proper ventilation because when we breathe out in a room, the air in the room becomes warm and impure. The warm air is less dense so it rises up and moves out through ventilators. Thus the cold fresh air comes in the room through the windows to take its place.
