Which gas is classified as LPG?

Propane is classified as a type of Liquefied Petroleum Gas (LPG). LPG is composed primarily of propane and butane, both of which are hydrocarbon compounds derived from natural gas processing and petroleum refining. Propane has a variety of uses including heating, cooking, and as fuel for engines and appliances due to its ability to easily liquefy under pressure, making it transportable and convenient for various applications.

The other gases listed, while they are also hydrocarbons, do not fit the classification of LPG. Ethane and hexane, for example, are not part of the LPG category. Methane, although it is a common fuel used in many applications, is considered a natural gas rather than an LPG. This distinction is important for understanding fuel types and their applications in different contexts.
