New to physics SE (physics too). Today I Observed a strange thing. In my house there are a pair of doors attached to same wall (the wall is about 30 cm wide), both are oppositely hinged (note: we need to push one door to close and other door to open). In this case when I open one door quickly, the other door closes. If I close the same door, the other door opens. what causes this? IS this due to pressure difference? or something else?

with opposite hinges, pulling one door open raises the air pressure inside the room for just a moment, which pushes the other door shut, and the opposite is true too. If you open a window in that room you will note that this effect will either go away or be made much weaker.
