Why is a ventilator provided in a room?
Ventilator is provided in a room for proper ventilation because when we breathe out in a room it becomes warm and air inside the room becomes impure. The warm air is less dense and rises up and moves out through the ventilator. So cold, fresh air comes inside the room through windows to take its place. Thus, the continuous circulation of fresh air keeps the air in the room fresh.
