Let's clear up this common question in simple terms. LPG is a unique substance that can exist as both a liquid and a gas, depending on its temperature and pressure. When LPG is stored in cylinders, it is actually stored as a liquid. Here's why:
You should know by now that LPG is a mixture of propane and butane gases. To turn these gases into a liquid form for storage and transportation, they undergo a process called liquefaction. This process involves cooling the gases to a temperature where they condense into a liquid state. So, in a sealed LPG cylinder, the liquid is kept under pressure to maintain its liquid state. The pressure inside the cylinder keeps the LPG in its condensed form, even though it would typically vaporize into a gas at normal atmospheric pressure.
However, despite being stored as a liquid, LPG retains its ability to vaporize back into a gas when released from the cylinder and exposed to atmospheric pressure and temperature. This dual-phase existence is what makes LPG such a versatile fuel for various applications, including cooking, heating, and powering vehicles.
There you have it. LPG is stored in cylinders as a liquid, thanks to the liquefaction process and pressure within the cylinder. However, it can easily vaporize back into a gas when released, allowing for efficient and convenient use in a wide range of applications.
