Ventilators are provided near ceilings in the rooms of our houses because the hot air is lighter and rises out of the room through the ventilators. Cool fresh air rushes into the room through the doors and windows to occupy its place.
{Hot air is less dense compared to cold air. So the warm air rises and the cool air is dense/heavy, thus remains down.}
