If room A is connected to the outside with a window and room A has a fan on; Would the air would try to move out from room A to the outside because there is a higher pressure inside the room?

ohhz that makes sense, I guess the pressure would already be equalized in the room if a window is open. Which makes me think that if you had a sealed room and a fan on, maybe you could build up pressure over a span of time and then open the window which would let basically all the pressure out?
... now if the room isn't sealed and air can come in via doorway/cracks in walls etc, what do you think will happen to the air pressure in the room ?
If I built up the pressure with sealing the cracks in my door, and closing the windows. Then I open a window to let the pressure out hopefully i could then sneakly try and trick the air under my door to come inside and drag in air because its also being sucked out the window?
sorry HallsofIvy I am kinda baked so I am gunna play this game with davenn to understand it more :P

A household fan can't create a meaningful pressure differential and by brownian motion, smells can travel against the airflow surprisingly well.
Air pressure is the force exerted by the weight of air molecules in a specific area. In a room with a window and a fan, air pressure can be affected by the movement of air from the fan and the opening or closing of the window. This can result in changes in temperature and ventilation within the room.
The size and placement of the window can greatly impact air pressure dynamics in a room. A larger window allows for more air flow and can create a draft when open, while a smaller window may have less of an impact on air pressure. The placement of the window also affects air flow, as a window positioned near the fan can create a stronger breeze.
The rotation speed of a fan can greatly impact air pressure dynamics in a room. A higher rotation speed can create a stronger breeze and increase air flow, while a lower rotation speed may have a less noticeable effect on air pressure. It is important to consider the size of the room and the fan's rotation speed when trying to control air pressure dynamics.
Yes, air pressure dynamics in a room can be affected by temperature changes. When warm air rises, it creates an area of low pressure, while cooler air sinking creates an area of high pressure. This can result in changes in air flow and ventilation within the room. The placement and operation of the window and fan can also impact how temperature changes affect air pressure dynamics.
Understanding air pressure dynamics in a room can be beneficial for creating a comfortable and efficient environment. By controlling air flow and ventilation, it is possible to regulate temperature and humidity levels in the room. This can result in a more comfortable and healthy living or working space. Additionally, understanding air pressure dynamics can also help with energy efficiency, as proper ventilation and air flow can reduce the need for heating and cooling systems.
