Liquefied petroleum (LP) gases primarily include which two gases?

Liquefied petroleum (LP) gases primarily include propane and butane. These two hydrocarbons are derived from fossil fuels and are commonly used as fuel sources in heating, cooking, and various industrial applications.

Propane is known for its high energy content and is often used in residential heating and outdoor grilling. Butane, on the other hand, is often utilized in portable fuel applications, such as lighter refills or camping stoves. Both gases can be liquefied under pressure, which makes them convenient for storage and transportation.

Understanding the characteristics and uses of propane and butane is crucial for safely handling and utilizing LP gases in various contexts, especially in compliance with safety standards and regulations. Other gases listed in the options, such as methane and ethylene, do not fall under the definition of liquefied petroleum gases. Methanol and ethane also serve different purposes and do not represent the typical constituents of LP gases.
