What happens to LPG when it is liquefied?

When LPG (liquefied petroleum gas) is liquefied, it is subjected to high pressure which causes it to transition from a gaseous state to a liquid state. This process involves compressing the gas, allowing it to be stored and transported more efficiently. The pressurization of LPG helps to keep it in a liquid form until it is released from its container, where it then expands and turns back into gas upon atmospheric release.

The nature of LPG allows it to remain highly flammable even in its liquefied form, and while liquid LPG can exist at low temperatures, it does not turn into a solid under normal conditions. Once released from pressure, LPG rapidly evaporates, but the correct characterization of what happens to it during the liquefaction process specifically emphasizes the role of pressurization.
