When "bleeding" an oxygen tank, you are releasing excess pressure stored in the regulator, not the tank itself. If the excess pressure remains, it can damage the regulator, and the guage needle can get stuck, giving an inaccurate reading of how much oxygen remains in the tank.
Using a pressure guage to determine the pressure of the gas inside, as thepressure decreases you can tell that it is getting empty. Another way is if you know the weight of the empty cylinder weigh the cyleinder and the difference gives you how much nitrogen is in it.
You must use the perfect gas law, which states that PV=nRTP= pressureV= volumen= number of molesR= universal gas constantT= temperaturerearranging the equation to solve for n we get n= PV/RTso n= 1.8(28.5)/8.314(298)n= 51.3/2477.572n= 0.021.09
It would contain about that much gas. As much as u put into it.
cutting to much trees will cause deforestation,desertification and overgrazing. this will also cause less oxygen.

They must be stamped on a label on side what max pressure.
The scissor blade has a slightly bigger area making the pressure on the object you are cutting much smaller
well you can control the pressure of it but by level, that depends on how much oxygen is in the tank. the easiest way to change the pressure of oxygen can be by heating or cooling the tank.
Such cylinders are made in a variety of capacities.
Whatever amount of pressure was used to compress the CO2 originally, can be reached (or nearly reached) when it is released into an air cylinder.
Four cylinder is 15 psi. Six cylinder is 40 psi.
In both places, 20% of the atmosphere is oxygen. However, in Denver the atmospheric pressure is lower, and the partial pressure of oxygen is lower, so less oxygen is available for respiration, and athletic performance there will be diminished.
Cost varies with size, pressure, and temperature requirements.
Oxygen is an element and can't really be chemically created. It can be separated out from compounds that contain oxygen ( water being most common ). People can survive on oxygen that has been separated out from other compounds.
Believe it or not, we can die from too little oxygen AND too much oxygen. This concept involves partial pressures. If we first consider using standard air (i.e. 20% Oxygen and 80% Nitrogen): (1 bar = 1 kilogram of pressure per square centimetre) At the surface - Total Pressure of air = 1 bar - Pressure of Oxygen = 0.2 bar - Pressure of Nitrogen = 0.8 bar At 10m - Total Pressure of air = 2 bar - Pressure of Oxygen = 0.4 bar - Pressure of Nitrogen = 1.6 bar At 20m - Total Pressure of air = 3 bar - Pressure of Oxygen = 0.6 bar - Pressure of Nitrogen = 2.4 bar At 30m - Total Pressure of air = 4 bar - Pressure of Oxygen = 0.8 bar - Pressure of Nitrogen = 3.2 bar At 40m - Total Pressure of air = 5 bar - Pressure of Oxygen = 1.0 bar - Pressure of Nitrogen = 4.0 bar At 50m - Total Pressure of air = 6 bar - Pressure of Oxygen = 1.2 bar - Pressure of Nitrogen = 4.8 bar At 60m - Total Pressure of air = 7 bar - Pressure of Oxygen = 1.4 bar - Pressure of Nitrogen = 5.6 bar At 70m - Total Pressure of air = 8 bar - Pressure of Oxygen = 1.6 bar - Pressure of Nitrogen = 6.4 bar It is at the partial pressure of 1.6 bar (which occurs at 70m where oxygen becomes toxic. That is why most dive organisations recommend 50m as a maximum for recreational diving. However, if pure oxygen is used: At surface - Pressure of Oxygen = 1 bar At 10m - Pressure of oxygen = 2 bar The oxygen has already become toxic! Hope that answers your question. The concept is called "partial pressures" and "oxygen toxicity" if you want to research more on a search engine.
