Answer :
Final answer:
Oxygen tanks are considered full at a specific pressure usually around 2000 to 3000 PSI, with a burst pressure higher to provide a safety factor. The bursting pressure would not be realistic at 2200 PSI if the tank is full at 2000 PSI, as it doesn't provide a substantial safety margin. The Ideal Gas Law is used to predict gas behavior under different conditions.
Explanation:
The question provided asks about the pressure at which an oxygen tank is considered full and the pressure at which it may burst. In Physics, pressure is a critical aspect when dealing with gases and containers. The safety of containers holding gases under pressure, such as scuba tanks or oxygen cylinders, is of paramount importance, and they are designed to withstand specific pressures.
A typical oxygen tank is considered full at a pressure that is specified by the manufacturer or regulatory standards, commonly around 2000 to 3000 PSI. The bursting pressure, or the pressure at which the tank may fail, is generally higher to provide a safety margin. For instance, a tank with a working pressure rated at 3000 PSI might burst at a pressure of around 1.5 to 2 times that amount, depending on the safety factor used in its design. Therefore, an oxygen tank that is full at 2000 PSI would not burst at 2200 PSI, as this would be too close to its full pressure and not offer a substantial safety factor.
To address the scenarios listed in the question:
- Full at 2000 PSI likely refers to the working pressure for which the tank was designed.
- Bursts at 2200 PSI would not be realistic as it does not provide a substantial safety margin over the full pressure.
- Full at 2200 PSI may represent a slightly higher standard full pressure for some tanks.
- Bursts at 2000 PSI is incorrect since the tank should not burst at the pressure it is filled to.
Finally, when studying the behavior of gases under different pressures and temperatures, the Ideal Gas Law is often used: PV = nRT, where:
- P is the pressure,
- V is the volume,
- n is the moles of gas,
- R is the ideal gas constant, and
- T is the temperature.
This law helps predict how gases will behave when subjected to changes in pressure, volume, and temperature, which is critical in the safe handling of high-pressure gas containers. Actual pressure ratings should always be obtained from the tank manufacturer or relevant regulations.
