Final answer:
The minimum static pressure for carbon dioxide (CO₂) depends on its application and state of matter, requiring reference to manufacturer’s guidelines or safety regulations for accurate information.
Step-by-step explanation:
Understanding the Static Pressure of Carbon Dioxide (CO₂)
When discussing the static pressure of carbon dioxide, or any gas for that matter, it is important to refer to the context in which the pressure is measured or required. The static pressure for a gas can vary depending on its state of matter (solid, liquid, or gas) and temperature. The minimum static pressure specified for carbon dioxide in use may be tied to its application, including storage and transportation requirements.
Carbon dioxide storage cylinders need to maintain a certain minimum pressure to ensure the CO₂ remains in the appropriate state. Industry standards or regulations often specify this minimum pressure. For instance, CO₂ for beverages is typically stored under a pressure of 5.0 atm. The relevant pressure for safe handling and operation is usually indicated on the cylinder or documentation accompanying the gas.
The minimum static pressure of CO₂ may differ in medical or industrial settings, depending on the equipment and application. Without a specific context, indicating a uniform minimum static pressure of 20 psi or 40 psi for CO₂ could be misleading. It is always essential to refer to the source of the query — such as manufacturer’s guidelines, safety regulations, or a phase diagram — to accurately address the minimum static pressure for CO₂.
