LPG, or liquefied petroleum gas, is a flammable mixture of hydrocarbon gases, primarily propane and butane. It is commonly used as fuel for heating, cooking, and vehicles. LPG is stored in liquid form under pressure and can be easily transported in tanks or cylinders. When released from its container, LPG vaporizes and can be used in various applications, including residential heating and industrial processes. It is considered a cleaner alternative to other fossil fuels, producing fewer emissions when burned. Safety measures are essential when handling LPG due to its flammable nature.
