How come when the window in a room open and you shut the door it slams shut?

Answer 1

The air shifts when you open the window....

Answer 2

If the window were closed, the room has no air flow. Closing a door with the window open allows the air in the room to flow through the window instead, causing the door to slam. There's just no resistance to the door when the window is open.

Answer 3

Air pressure. The wind blowing in is stronger than the pressure of air in the room, when the door opens (the door being bigger and than the window), the built up pressure tries to escape, creating a draft or vaccuum, when the door starts to close the suction pulls it shut faster and it slams.

Answer 4

That's caused by the air pressure outside that makes the door slam shut. See if the window was closed, you'll have no other pressure other than whats in the room.

Answer 5

This phenmoena of great mystery is a draft. Air pressure in the room isn't equal to the outside air presure. There is a natural tendency to equalize the pressure, so mass of air from the higher air pressure region comes to the lower air pressure region (this is how wind is created) and it pushes the door to shut.

Answer 6

So change into it windy on the time?. that could want to have blown your door close, as you're saying, and once you opened it lower back and went into your mothers and fathers room, change into their window open?. If both yours and theirs change into open, might want to have cerated a bypass-draft, which may have slammed yours close lower back, also the wind might want to describe the undesirable line. What do you recommend by "Then I checked the closet- it change into closed in a peculiar way- yet not something change into there."??. How can a door be closed in a 'extraordinary' way?. i'm guessing that the wind might want to have closed/opened that too, if it change into blowing out of your window by for your mothers and fathers window and out lower back.

Answer 7

The flow of air is caused by a difference in air pressure. The air moves from a high energy state (high pressure) to a lower energy state (low pressure). This is only one example of a universal principle. Another example would be electricity where current moves from high voltage to low voltage.
If you have a difference of anything expect movement to occur if the path is there.

Answer 8

Air pressure

Answer 9

Theres a draft, like a suction in the open window!

Answer 10

Air pressure.
