Compressed air pressure equals what volume?

Use Boyle's Law for that. Assuming the temperature is always constant, the product of pressure and volume is always constant.\n\nP * V = k\nor\nP1 * V1 = P2 * V2\n\nIf temperature is included in the equation, you could either use the combined gas law or the ideal gas law.\n\nNote: Elevation plays a significant role in Boyle's Law so it will have a difference in the gauge readings if you relocate it from sea level to the mountaintop.

Pressure is nothing but a force applied onto an area. Pressure in air filled balloon, for example,  is due to "concurrent forces" created by compressed air pushing outward from the center on the balloon. These forces are equal in strength that at the center they clear each other. Thus at the center the pressure is a nonsatble 0.

The amount of material and the prevalent temperature haven't changed much, so the pressure and volume are inversely proportional.  As the external pressure on the balloon decreases, the amount of material in the balloon will expand to equalize that pressure.

Expansion coefficients for air can be determined using the attached link.\n\nBest wishes !

Pressure * volume = number of mol * temperature (in ^oK) * 8.314\n\nYou have all the information you need right there. \nFirst solve for n for the initial state. \nSince you haven't added any more material you can then use the same value of n for the second state and solve for P.\n\nThis is sixth grade algebra. Anyone being asked to solve gas equations had better be able to do it standing on their head or they are in real trouble.

Use the formula: \n\nPV(1)=PV(2) where P is pressure and v is volume.\n\n400(1)=(2000)x(P)\n\nSolving, P =.2atm\n\nPS: If you ever forget the formula, use common sense. When you place any gas under pressure, what happens to its volume? It goes down, because the pressure is forcing the gas into a smaller volume. So when you increase your gas volume by 5 (400x5=2000) you must lower that pressure by the same amount. So the pressure goes down by 5 (1/5=.2).

It is filled with air.  It has a circumference of 27-28 inches with a weight of 14-16 ounces.  It should have the air pressure of 8.5 to 15.6 PSI.

In the relationship between pressure, temperature and volume of gases, the pressure and temperature have a direct relationship....if one factor goes up so does the other one.  So, set up what you know as a ratio.\n\npressure/temperature = pressure/temperature\n\n400/80  =   300/x       cross multiply and solve for unknown\n\n24000 = 400x\n\n60 = x

mozart is wrong, carbon-based is right. 1 litre of compressed air will weigh more than 1 litre of normal atmospheric pressure air. Compress it enough and it will become liquid, then solid. However, if you take 1 litre of air and you compress it to a smaller size, it still weighs the same.
