Calculate the area of the room. Calculate the area of the window (or whatever opening) Room Area*100/Window Area
100%. All of the oxygen that I breathe comes from the air! The answer that you were probably after, but did not ask, was about the percentage of oxygen in the air that we breathe. The questions may sound similar but they are not the same. The answer is a little over 20%.
2.66666666667 is the decimal of oxygen in the air
That would depend on the size of the room and the humidity.
Room air is about 21% oxygen.
Oxygen has, because the people in the room, as they breathe, are constantly replacing it with carbon dioxide. That's why it's so important to have adequate ventilation and air replacement in crowded confined spaces.
If you can breathe in the room the incubator is located in then you will not need to supplement the air they need. Incubators are not airtight.
air fresheners can give a fresh scent to the entire room because vapor can diffuse into air.
Oxygen comprises about 21% of fresh air. Room air is nearly always refreshed from outsides sources sufficiently fast for this value to hold true. However, if ventilation is extremely poor it can differ.
Air does indeed take up room. Air molecules have a mass that takes up whatever room it is confined to.
Why is there humidity in the room when air conditioner is cooling? Room feels damp.
the gas in the room freshener mixes with the air in the room and as air moves , the smell from the room freshener spreads through out the room
The mass of air in a room depends on how big the room is, the air pressure at the given moment, how pure the air (is it next to a coal-burning power plant?), what planet the room is on, etc.
A basic split air conditioner recirculates cool air in to the room.
The percentage of nitrogen in pure, dry ,standard air is 78,084 % (by volume).
The reason people use air conditioning is to cool a room by cooling the circulating air in that room
