So my brother and i were fighting over what happens when we open the door that leads outside. Are you letting the hot air in or the cold air out?? Stupid question to fight over >.< Post what you think.

"my pokemon brings all the boys to the yard and they're like "lets trade some cards" darn right, lets trade some cards ill trade you, but not charzard"

that should help

both, really

it's a matter of which side has more air pressure at any given moment, but given that the pressure's bound to fluctuate between the two and breezes happen and whatnot, the two will just intermix

also, the two will change each others' temperature as they bang up against each other.

Basically, the question is predicated on pretty vast amounts of simplification of the forces at work.

The air movement will fluctuate but the important part is that the heat will flow from a hotter place to a colder place.

It did help.

Cold air does not exist.

lmao

also, depends where the pressure is greater

Good answer!
