What physical property is important to consider when storing CNG?

• A. It must be stored at high temperatures.
• B. It must be stored at high pressures.
• C. It must be stored in open containers.
• D. It requires minimal storage space.

Answer: (B)

When storing compressed natural gas (CNG), the critical physical property to consider is that it must be stored at high pressures. This is because CNG is gaseous at standard temperature and pressure, occupying a much larger volume than it does when compressed. High-pressure storage allows CNG to be kept in a more manageable, dense state, facilitating its use as an energy source for various applications, including vehicles. Storing CNG at high pressures is essential for practical and efficient storage and transportation because it enables a greater amount of gas to be contained in a smaller space. This is particularly important in automotive applications, where storage space is limited, and the energy density required for performance must be maintained. While certain factors such as safe temperatures and container types are also important in the overall management of CNG storage, high pressure is the primary factor that directly influences the gas's physical state and storage requirements, making it the most critical consideration.
