Question: n2 is found in a litre flask?
Answer: N2 is found in a 1-litre flask under 100 kPa pressure and O2 is found in another 3-litre flask under 320 kPa pressure. If the two flasks are connected, what is the resultant pressure? There are 40 ml of air in a large syringe. With the exit hole plugged, you squeeze the air down to about 10 ml.
