Why does the door close more easily when the window is open?

[Passions]

Any good answer?

I don't know how to explain it in technical terms, but basically when you leave the window open you allow air to rush out of it. If you have the window up it has nowhere to go but outside the door, making it harder to get a seal.

When you close the door it puts positive air pressure in the house. When the window is open there is an escape for the extra air being forced in by the closing door. Get it?


edit because I misspelled "get"😱

edit because I misspelled "because" in my previous edit😱😱

The volume of air being moved is easier displaced out the window as the door closes instead of trying to rush through a closing door.

All you have to know is that air movement from the outside inward or inside outward is easier.

And air movement between two rooms with no open windows is a lot harder.
