What is LP gas primarily made up of?

LP gas, or liquefied petroleum gas, is primarily made up of propane and butane. These hydrocarbons are typically produced during the refining of crude oil and the processing of natural gas. Propane and butane are favored for their high energy content, which makes them efficient fuels for heating, cooking, and powering various types of equipment and appliances.

In contrast, other gases listed in the choices serve different purposes or are not components of LP gas. Methane and ethane, commonly associated with natural gas, do not make up LP gas. Carbon dioxide and nitrogen are non-combustible gases that are not used as fuel in this context. Hydrogen and oxygen can participate in combustion reactions, but they do not constitute LP gas. Understanding the composition of LP gas is crucial for applications in energy supply and safety considerations in handling and storage.
