Which gas is primarily composed of propane and can be liquefied under moderate pressure?

Liquefied Petroleum Gas (LP-Gas) is primarily composed of propane and can be easily liquefied under moderate pressure. This gas is commonly used for heating, cooking, and as fuel for certain vehicles. The ability to liquefy LP-Gas at relatively low pressures makes it an efficient option for storage and transportation, as it can reduce the volume significantly. When in liquid form, LP-Gas can be stored in tanks and then vapored back into gas form for use.

Other types of gases mentioned, such as Natural Gas and Compressed Natural Gas, primarily consist of methane, while Synthetic Gas can be created from various feedstocks but does not specifically refer to propane as its main component. Understanding the characteristics of LP-Gas highlights its versatility and importance in various applications.
