Suppose a hole is drilled into the wall of a room which is originally completely evacuated. In the adjacent room, from which the hole is drilled, the pressure of the ambient air is 1 atm and the temperature is 300k. Air contains 21% oxygen and 79% nitrrogen by mole. If one collects the first liter of gas that moves from the original room into the evacuated room, approximately what would you expect its composition to be? Would it be the same as regular air?
